When upgrading gt on an existing installation without .installed.json,
formulas that exist but don't match embedded were incorrectly marked as
"modified" (implying user customization). Now they're marked "untracked"
and are safe to update since there's no record of user modification.
This improves the upgrade experience:
- "modified" = tracked file user changed (skip update)
- "untracked" = file exists but not tracked (safe to update)
Adds 3 new tests for untracked scenarios.

Adds infrastructure to automatically update embedded formulas when
the binary is upgraded, while preserving user customizations.
Changes:
- Add CheckFormulaHealth() to detect outdated/modified/missing formulas
- Add UpdateFormulas() to safely update formulas via gt doctor --fix
- Track installed formula checksums in .beads/formulas/.installed.json
- Add FormulaCheck to gt doctor with auto-fix capability
- Compute checksums at runtime from embedded files (no build-time manifest)
Update scenarios:
- Outdated (embedded changed, user unchanged): Update automatically
- Modified (user customized): Skip with warning
- Missing (user deleted): Reinstall with message
- New (never installed): Install
