- Add checkStaleBinaryWarning() call to persistentPreRun (was only in
deprecated function)
- Fix GetRepoRoot() to look in correct location ($GT_ROOT/gastown/mayor/rig)
- Use hasGtSource() with os.Stat instead of shell test command
Agents will now see warnings when running gt with a stale binary.

Add detection for when the installed gt binary is out of date with the
source repository. This helps catch issues where commands fail mysteriously
because the installed binary doesn't have recent fixes.
Changes:
- Add internal/version package with stale binary detection logic
- Add startup warning in PersistentPreRunE when binary is stale
- Add gt doctor check for stale-binary
- Use prefix matching for commit comparison (handles short vs full hash)
The warning is non-blocking and only shows once per shell session via
the GT_STALE_WARNED environment variable.
