49de1adc49 fix(desktop): detect Python via registry/filesystem; pin to 3.11–3.13
Two related fixes for Python detection on Windows:

1. py.exe (Python launcher) is missing from per-user installs that
   didn't check the launcher option, so 'py -3.X --version' alone
   misses real Python installs. User-reported case: clean Win11 +
   official Python.org 3.14 install -> 'where py' returned nothing,
   our installer offered to install Python again. Both NSIS prereq
   page and main.cjs now probe in this order:
     1. py.exe launcher (when present)
     2. PEP 514 registry: HKLM/HKCU\SOFTWARE\Python\PythonCore\<v>\InstallPath
     3. Filesystem: %ProgramFiles%\Python<v>, %LocalAppData%\Programs\Python\Python<v>
   Crucially, we never fall back to running 'python.exe' from PATH
   on Windows — the WindowsApps stub at %LOCALAPPDATA%\Microsoft\
   WindowsApps\python.exe is a redirector that opens the Microsoft
   Store window if no Store Python is installed. Triggering that
   during boot would be terrible UX. Registry/filesystem probes
   never execute the binary.

2. Drop 3.14 from the supported version set. Several Hermes deps
   (notably pywinpty, which carries Rust crates like
   windows_x86_64_msvc) don't yet publish 3.14 wheels. With wheels
   missing, 'pip install -e .' falls back to building from sdist,
   which needs a Rust toolchain — users see 'could not compile
   windows_x86_64_msvc build script' on first run. install.ps1
   sidesteps this by pinning to 3.11 via uv; the desktop installer
   doesn't yet have the same uv-managed-Python pathway, so for now
   we accept 3.11/3.12/3.13 and tell winget to install 3.11 if
   none of those are present. Revisit when the wheel ecosystem
   catches up to 3.14 (~early 2026).

96968c9932 fix(desktop): add 2u clearance below prereq checkboxes
Group box bottom border was clipping the checkboxes by 1-2px.
Bumped each box height 26u→30u; checkboxes now sit 2u above the bottom border.

32f0fde35c feat(desktop): add ripgrep to NSIS prereq page + polish layout
Add ripgrep as a third (recommended) prereq alongside Python and Git in
the NSIS prereq detection page, and clean up the page layout based on
on-VM testing.

Why ripgrep
- Hermes' search_files tool calls `rg` directly for content + filename
  search (tools/file_operations.py:1382). Falls back to grep/find from
  Git Bash when missing — works but slower and noisier (no .gitignore
  awareness).
- ~5MB winget install via `BurntSushi.ripgrep.MSVC --scope user` — no
  UAC prompt, parallel to how Python installs.
- scripts/install.ps1 already installs ripgrep as part of
  Install-SystemPackages; this brings the desktop installer to parity.

Why "recommended" not "required"
- Python and Git are hard requirements: without them the agent runtime
  or terminal tool refuses to start. The bootstrapper preflight throws.
- ripgrep is a performance enhancement: missing it just means slower
  searches. Page wording reflects this; failure to install is logged
  but doesn't show a MessageBox or block.

Layout polish (response to on-VM screenshot review)
- Wizard header now correctly reads "System Requirements" instead of
  the leftover "Choose Install Location" from the previous page. Set
  via `GetDlgItem $HWNDPARENT 1037/1038` + WM_SETTEXT — the standard
  NSIS pattern for overriding the page header on a custom Page.
- Removed redundant in-body title + verbose intro paragraph; the
  wizard header IS the title now. Body has one short intro line.
- Group boxes tightened to 26u with content positioned just below the
  groupbox title (not top-anchored status + bottom-anchored checkbox
  with empty space in the middle). All three panels + footer fit
  comfortably in 126u, well under the 140u page limit.
- Checkbox labels simplified: dropped "(per-user, no admin prompt)"
  and "(administrator approval required)" suffixes. The footer note
  still calls out UAC for Git when relevant.
- Footer text trimmed to fit cleanly without clipping.

Install order (in customInstall macro)
- Python → ripgrep → Git
- Python and ripgrep are silent and run first; Git's UAC prompt comes
  last so the user's approval interaction isn't interrupted by silent
  activity afterwards.

Skip behavior unchanged
- All three detected → page auto-skips via Abort
- Silent install (/S) → customInstall winget block skips
- User unchecks all → page advances without running winget

Files
- apps/desktop/installer/prereq-check.nsh: ripgrep detection block,
  ripgrep page panel + checkbox, ripgrep customInstall block,
  GetDlgItem header override, layout reflow
- apps/desktop/README.md: Runtime prerequisites section updated to
  list ripgrep as recommended, with manual winget command

c8c8c53a0c feat(desktop): NSIS prereq detection page + auto-install via winget
The packaged Windows installer now detects Python 3.11+ and Git for Windows
at install time and offers to install missing prereqs via winget. Mirrors
the prereq logic scripts/install.ps1 already runs for CLI installs, so
desktop installer users get the same out-of-the-box experience as
install.ps1 users.

Why
- Hermes' terminal tool calls bash.exe directly (tools/environments/
  local.py); on Windows that's Git Bash from Git for Windows. Without it,
  the agent fails on the first terminal() call.
- Hermes' Python runtime needs 3.11+. Without it, the desktop bootstrapper
  errors out at venv creation.
- Both gaps surfaced on a fresh Windows 11 VM smoke test: VM had Python
  pre-installed but no Git, so the agent's first terminal call failed
  with "Git Bash isn't installed."
- install.ps1 has had Install-Git + Install-Uv functions for ages. The
  desktop installer was the asymmetric outlier.

How — NSIS prereq page
- New file: apps/desktop/installer/prereq-check.nsh (plugged into
  electron-builder via build.nsis.include)
- Real Wizard page using nsDialogs, inserted via customPageAfterChangeDir
  hook (between the Directory page and InstFiles).
  - Group boxes for Python and Git, each showing detection status.
  - Pre-checked install checkboxes when winget is available.
  - Auto-skips silently if both prereqs are already installed.
  - Falls back to manual download URLs when winget itself is missing.
- Detection:
  - Python: probes `py -3.11`/`-3.12`/`-3.13`/`-3.14` via the Python
    launcher. Microsoft Store "Python stub" (no py.exe) is correctly
    classified as not-installed.
  - Git: `where git`.
  - winget: `where winget` (Win10 1809+ / Win11 with App Installer).
- Install execution (in customInstall macro):
  - Python: nsExec::ExecToLog with `--scope user --silent`. Per-user
    install, no UAC prompt, output streams to install log.
  - Git: ExecShellWait via Windows ShellExecute. Critical because Git
    always installs per-machine and triggers UAC; ShellExecute preserves
    the foreground focus chain across non-elevated → elevated process
    spawns, so UAC actually comes to the foreground. nsExec::ExecToLog
    breaks the chain because winget runs hidden.
  - Both pass `--disable-interactivity --accept-package-agreements
    --accept-source-agreements` to suppress winget's own dialogs.
- Verification: probes Git's standard install locations via FileExists
  rather than `where git`. NSIS's process inherits PATH at startup, so
  a freshly-installed Git won't be visible to `where` until restart.
- Silent installs (/S) skip the prompts; managed deploys handle prereqs
  out-of-band via Group Policy / Intune.

How — Electron-side safety net
- New findGitBash() in main.cjs, parallel to findSystemPython(). Probes
  the same locations as tools/environments/local.py:_find_bash() so a
  positive result here means the agent's terminal tool will work.
- ensureRuntime now throws a clear, actionable error on Windows when Git
  Bash isn't found, matching the existing "Python 3.11+ is required"
  error path.
- Catches users the NSIS page doesn't: .msi installer users (NSIS prereq
  page doesn't run for MSI), `npm run dev` users, manual installers,
  anyone who unchecked the install boxes on the NSIS prereq page.
- All gated on `IS_WINDOWS`; macOS / Linux unaffected.

NSIS build issue (resolved)
- electron-builder defaults to `-WX` (warnings as errors). NSIS optimizer
  emits "warning 6010: function not referenced" for our page functions
  because Page custom directives don't count as references in its
  static-analysis pass. The functions ARE called at runtime when NSIS
  invokes the page; the optimizer just can't see it statically.
- Set `build.nsis.warningsAsErrors=false` in package.json so this
  spurious warning doesn't fail the build. (Documented option from
  electron-builder's nsisOptions.)

Out of scope (filed for future work)
- MSI prereq detection: Windows Installer custom actions are a different
  mechanism. Enterprise deploys typically handle prereqs via GP/Intune.
- Bundle PortableGit + python-build-standalone in extraResources for
  zero-network installs. ~80MB increase.
- Mac / Linux GUI prereq flows (different installer formats; Xcode CLT
  covers most macOS prereqs already; Linux is per-distro hard).

Files
- apps/desktop/installer/prereq-check.nsh   (new, ~290 lines NSIS)
- apps/desktop/package.json                 (build.nsis.include +
                                              warningsAsErrors)
- apps/desktop/electron/main.cjs            (findGitBash + preflight)
- apps/desktop/README.md                    (Runtime prerequisites
                                              section)

Cross-platform impact
- macOS / Linux builds (dist:mac, dist:mac:dmg, dist:mac:zip): nsis
  config is ignored entirely; .nsh is dormant.
- npm run dev: .nsh dormant; main.cjs preflight gated on IS_WINDOWS.
- scripts/install.ps1, scripts/install.sh: no reference to any new
  files; CLI install paths untouched.
- Hermes CLI / dashboard / gateway: no reference; runtime untouched.
- All checks: node --check on main.cjs and test-desktop.mjs pass;
  npm run test:desktop:platforms 4/4 passing; node --test green.

Tested
- npm run dist:win produces signed .exe and .msi without errors.
- Fresh Win11 VM (Python pre-installed, no Git): prereq page renders,
  Python check shows detected, Git checkbox pre-checked. Click Next →
  Git installs via winget with UAC prompt in foreground.
- After install completes, Hermes launches and the agent's terminal
  tool can run bash commands. Verified Git Bash is detected at
  `C:\Program Files\Git\bin\bash.exe` by ensureRuntime's preflight.
