Installing kyberforge via the holocron marketplace caches the plugin at a
specific version. After every push, the marketplace clone and plugin cache
need to be refreshed manually — otherwise new skills added since the last
install are invisible until the user runs `claude plugin update` manually.
Adds a post-push git hook that pulls the holocron marketplace clone and
updates the kyberforge cache automatically after every push, eliminating
the manual refresh step.
## Implementation Notes
- `scripts/git-hooks/post-push` is the canonical source; `install.sh` now
copies all files in `scripts/git-hooks/` into `.git/hooks/` on fresh
checkouts, making the pattern extensible for future hooks.
- Hook exits 0 on all failures (warns to stderr) — a stale cache refresh
never blocks a completed push.
- 11 bats tests cover both the hook and the install.sh copy block, using
mocked binaries and a temp-tree fixture to avoid touching real state.
