beads/crew/lizzy 2fe15e2328 feat(hooks): add jujutsu (jj) version control support ...

Add detection and hook support for jujutsu repositories:

- IsJujutsuRepo(): detects .jj directory
- IsColocatedJJGit(): detects colocated jj+git repos
- GetJujutsuRoot(): finds jj repo root

For colocated repos (jj git init --colocate):
- Install simplified hooks without staging (jj auto-commits working copy)
- Worktree handling preserved for git worktrees in colocated repos

For pure jj repos (no git):
- Print alias instructions since jj doesn't have native hooks yet

Closes: hq-ew1mbr.12
