chore: merge origin/main, resolve VERSION + CHANGELOG conflicts

 - **Vendoring is deprecated.** README no longer recommends copying gstack into your repo. Global install + `--team` is the way. `--local` flag still works but prints a deprecation warning.
 - **Uninstall cleans up hooks.** `gstack-uninstall` now removes the SessionStart hook from `~/.claude/settings.json`.

+- **Skill prefix self-healing.** Setup now runs `gstack-relink` as a final consistency check after linking skills. If an interrupted setup, stale git state, or upgrade left your `name:` fields out of sync with `skill_prefix: false`, setup will auto-correct on the next run. No more `/gstack-qa` when you wanted `/qa`.

 ## [0.15.6.0] - 2026-04-04 — Declarative Multi-Host Platform
 
 Adding a new coding agent to gstack used to mean touching 9 files and knowing the internals of `gen-skill-docs.ts`. Now it's one TypeScript config file and a re-export. Zero code changes elsewhere. Tests auto-parameterize.
