feat(git): support custom commit flags for app-run commits

[0xnim]

Related to #274.

What Changed

• Added support for passing extra git commit flags
• Added a Settings field for app run git commit flags, so users can configure flags like --no-gpg-sign

Why

T3 Code runs git commit non-interactively. On a machine with global commit.gpgsign=true, commits can fail because GPG prompts for a pass on /dev/tty, which does not exist in this case.

This PR does NOT add interactive GPG/password support. Instead its a small workaround fix, users can configure extra commit flags for app run commits, which makes setups like --no-gpg-sign possible without changing their global git config

UI Changes

Adds a new Settings field under Git for extra git commit flags

Before	After

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes
• I included a video for animation/interaction changes

Note

Add user-configurable extra git commit flags to app-run commits

• Adds a gitCommitFlags setting (max 4096 chars) to appSettings.ts and exposes a UI input in the settings route with warnings for non-flag tokens.
• Introduces tokenizeCommitFlags in GitManager.ts to parse raw flag strings into CLI tokens, filtering out any tokens that don't start with a dash.
• Threads the sanitized flags from GitActionsControl → runStackedAction mutation → GitManager.runCommitStep → GitCore.commit → git commit invocation.
• Risk: user-supplied flags are passed directly to git commit; only dash-prefixed tokens are filtered, but malformed flag values (e.g. --flag=value) are not further validated.
