Syed Abdur Rehman Ali f5b635f6ab feat(cli): recognise Shift+Enter as a newline key
Closes #5346.

Most terminals send the same byte sequence for `Enter` and `Shift+Enter`
by default, so the application can't tell them apart — this is a terminal
protocol limitation, not something Hermes can paper over. But terminals
that implement the Kitty keyboard protocol (Kitty / foot / WezTerm /
Ghostty by default; iTerm2 / Alacritty / VS Code terminal / Warp once the
protocol is enabled) DO emit a distinct sequence for `Shift+Enter`:

  - `\x1b[13;2u`     — Kitty / CSI-u, modifier=2
  - `\x1b[27;2;13~`  — xterm modifyOtherKeys=2

Stock prompt_toolkit doesn't have the CSI-u sequence in its
`ANSI_SEQUENCES` table at all, and it maps the modifyOtherKeys variant to
plain `Keys.ControlM` (Enter) — i.e. it strips the Shift modifier, which
is the bug users actually hit on iTerm2 and friends.

This PR adds `hermes_cli/pt_input_extras.install_shift_enter_alias()`,
called once at CLI startup from `cli.py`, which inserts/overwrites those
sequences in `ANSI_SEQUENCES` so they decode to `(Keys.Escape, Keys.ControlM)`
— the same key tuple `Alt+Enter` produces. The existing Alt+Enter newline
handler (`@kb.add('escape', 'enter')` in `cli.py`) then fires unchanged,
so there is no new keybinding to register and no behavioral change for
terminals that don't emit the distinct sequences.

Files
=====

* `hermes_cli/pt_input_extras.py` — new module hosting the helper. Lives
  outside `cli.py` so it's importable in tests without dragging in the
  full CLI runtime (which depends on `fire`, `rich`, etc.).
* `cli.py` — calls `install_shift_enter_alias()` once at module import.
  Wrapped in try/except so prompt_toolkit version drift can't break CLI
  startup.
* `tests/cli/test_cli_shift_enter_newline.py` — 6 tests:
  - registration of all three byte sequences
  - overwrite of stock prompt_toolkit's broken modifyOtherKeys mapping
  - idempotency
  - parser equivalence: CSI-u Shift+Enter == Alt+Enter
  - parser equivalence: modifyOtherKeys Shift+Enter == Alt+Enter
  - plain Enter remains a single key (submit), distinct from the two-key
    Alt+Enter / Shift+Enter tuple
* `website/docs/user-guide/cli.md` — keybinding table updated; new
  "Shift+Enter compatibility" subsection with a per-terminal status table
  noting macOS Terminal / stock Windows Terminal cannot distinguish the
  keystroke at the protocol level.
* `website/docs/getting-started/quickstart.md`,
  `website/docs/guides/tips.md` — short mention pointing readers at the
  full compatibility note in `cli.md`.

Tested
======

  pytest tests/cli/test_cli_shift_enter_newline.py        # 6 passed

Live-tested by triggering `\x1b[13;2u` against the running Vt100Parser
(see test). Not exercised in a real terminal end-to-end because that
requires a Kitty-protocol-capable host; the test exercises the parser
path that drives the live terminal too.

Website

This website is built using Docusaurus, a modern static website generator.

Installation

yarn

Local Development

yarn start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Build

yarn build

This command generates static content into the build directory and can be served using any static contents hosting service.

Deployment

Using SSH:

USE_SSH=true yarn deploy

Not using SSH:

GIT_USER=<Your GitHub username> yarn deploy

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.

Diagram Linting

CI runs ascii-guard to lint docs for ASCII box diagrams. Use Mermaid (````mermaid`) or plain lists/tables instead of ASCII boxes to avoid CI failures.
