Harden vscode/cursor install-hooks when IDE CLI is not in PATH

[Copilot]

When code/cursor CLIs aren't in PATH, extension installation silently fails with a warning. The CLIs are just shell script wrappers over Electron's cli.js — we can call it directly as a fallback.

Changes

• EditorCliCommand struct (utils.rs) — Encapsulates CLI invocation, handling both PATH binaries and the Electron + cli.js fallback (sets ELECTRON_RUN_AS_NODE=1, passes cli.js as first arg, handles Windows cmd /C wrapping)
• resolve_editor_cli(name) — Checks PATH first, then searches known OS-specific install locations:
  • macOS: /Applications/{Cursor,Visual Studio Code}.app/Contents/...
  • Linux: /usr/share/, /opt/, ~/.local/share/
  • Windows: %LOCALAPPDATA%\Programs\...
• is_vsc_editor_extension_installed / install_vsc_editor_extension — Now accept &EditorCliCommand instead of &str, using its command() builder
• cursor.rs / vscode.rs — Replaced binary_exists() + raw program name with resolve_editor_cli() in both check_hooks() and install_extras()

How the fallback works

The code/cursor shell scripts essentially do:

ELECTRON_RUN_AS_NODE=1 "$APP/Contents/MacOS/Electron" "$APP/Contents/Resources/app/out/cli.js" "$@"

resolve_editor_cli finds these paths directly when the wrapper script isn't in PATH, constructs the equivalent command, and uses it for version checks, extension listing, and extension installation.

<issue_title>Harden vscode/cursor install-hooks when the user doesn't have the IDE CLI installed in path</issue_title>
<issue_description>The code and cursor CLIs are just shell script wrappers over the core electron cli.js script. If the CLIs don't exist in the PATH we should try to mimic what the shell scripts do and call cli.js directly. This will ensure we get all extensions/hooked installed even when the CLIs aren't available</issue_description>
