fix(init): truncate uncommitted file list to first 5 entries (#381)

## Summary

- Truncates the uncommitted/untracked file list in the `init` git safety
check to show only the first 5 files
- Appends a summary line (e.g. `+ 12 more uncommitted files`) when there
are more than 5
- Prevents terminal flooding in repos with many dirty files while still
communicating the situation clearly

## Changes

**`src/lib/init/git.ts`** — In `checkGitStatus`, instead of joining all
files into the warning message, slice to `MAX_DISPLAYED_FILES` (5) and
append a remainder count if truncated. Both the `--yes` auto-proceed and
interactive prompt paths benefit from this.
