chore: standalone repo bootstrap after split from inkreach-teable monorepo

- untrack dist/, add .gitignore, add pnpm-lock.yaml
- inline tsconfig.base.json options (no monorepo extends)
- install.sh: CLI now at repo root; install skill to ~/.zcode/skills (user scope)
- fix stale paths in skill docs; 7 actions in help text; README

.gitignore
