windows-hermes-resolution.test.ts regexed main.ts source text to check
three Windows resolution bugs that caused desktop reinstall loops:
1. findOnPath()'s PATHEXT extension order (must try real extensions before
the empty one, or an extensionless Git-Bash hermes shim shadows
hermes.cmd/.exe).
2. handOffWindowsBootstrapRecovery()'s --update vs --repair choice (must
gate on any real-install signal, not just the hermes.exe shim).
3. unwrapWindowsVenvHermesCommand()'s probe-before-trust behavior (must
canImportHermesCli() before returning a venv python, or a broken venv
gets re-selected forever).
Extract all three into pure, dependency-injected functions in
windows-hermes-path.ts (no Electron import): buildPathExtCandidates(),
chooseUpdaterArgs(), resolveVenvHermesCommand(). main.ts's
findOnPath/handOffWindowsBootstrapRecovery/unwrapWindowsVenvHermesCommand
now call these with their existing helpers (fileExists, canImportHermesCli,
getVenvPython, etc.) passed through as deps.
windows-hermes-path.test.ts replaces windows-hermes-resolution.test.ts,
importing the pure functions directly and asserting real return values
with fake/injected dependencies (fake venvs, fake probes) -- no readFileSync,
no regex-on-source.
