chore: add gt operational directories to .gitignore

[jrf0110]

Summary

• Adds .gitignore entries for Gas Town operational directories (.runtime/, .claude/, .beads/, .logs/)
• Adds git-lfs husky hooks (post-checkout, post-commit, post-merge, pre-push)

Source

Polecat: chrome (branch polecat/chrome/hq-rim@mlmw0c0d)
MR: ki-cwh

Test plan

• Config-only change — no source code modified
• Rebased cleanly on main (already up to date)

SUGGESTION: Anchor ignore pattern to repo root to avoid accidentally ignoring nested .runtime/ directories

In a monorepo, .runtime/ without a leading slash will ignore that directory name anywhere, including inside subprojects. If this is intended to be root-only, consider anchoring with a leading /.

Suggested change

	.runtime/
	/.runtime/

WARNING: Hook hard-fails when git-lfs is not installed

This hook exits non-zero (exit 2) if git-lfs isn’t on PATH, which will block git push for contributors/CI environments that don’t have LFS installed. If LFS is required, consider ensuring installation is enforced via onboarding/CI and making the hook message non-blocking, or gating this behavior to only repos that truly require LFS for the push.
