shell: fish functions -> ~/.local/bin executables + bash/zsh ports; manage ~/.agents

- 16 cross-shell utilities converted to sh/bash chezmoi executables:
  ai c2p cp-appid extract_agents fab gdc gh-sonr-org-migrate ghg-clone
  ghn gho git-summary launch_omp_livediff_overlay lc-elir mdcp mdp pj
  (ghg-clone not named ghg: unrelated cargo binary owns that name)
- cwd/history helpers stay per-shell: yy c cd clip-last + ghg/ghn/gho
  cd-wrappers in bash/functions/ and zsh/functions/, loaded by rc files
- fish keeps only shell-state functions; converted ones now hit PATH
- cp-appid ignore gating moved to .local/bin path
- dot_agents/skills: 82 skills materialized from dotstate storage so
  dot_claude skill symlinks resolve on fresh bootstrap; dotstate
  profile/symlinks.json released .agents/skills .bashrc .zshrc

+name: setup-pre-commit
+description: Set up Husky pre-commit hooks with lint-staged (Prettier), type checking, and tests in the current repo. Use when user wants to add pre-commit hooks, set up Husky, configure lint-staged, or add commit-time formatting/typechecking/testing.
+---
+
+# Setup Pre-Commit Hooks
+
+## What This Sets Up
+
+- **Husky** pre-commit hook
+- **lint-staged** running Prettier on all staged files
+- **Prettier** config (if missing)
+- **typecheck** and **test** scripts in the pre-commit hook
+
+## Steps
+
+### 1. Detect package manager
+
+Check for `package-lock.json` (npm), `pnpm-lock.yaml` (pnpm), `yarn.lock` (yarn), `bun.lockb` (bun). Use whichever is present. Default to npm if unclear.
+
+### 2. Install dependencies
+
+Install as devDependencies:
+
+```
+husky lint-staged prettier
+```
+
+### 3. Initialize Husky
+
+```bash
+npx husky init
+```
+
+This creates `.husky/` dir and adds `prepare: "husky"` to package.json.
+
+### 4. Create `.husky/pre-commit`
+
+Write this file (no shebang needed for Husky v9+):
+
+```
+npx lint-staged
+npm run typecheck
+npm run test
+```
+
+**Adapt**: Replace `npm` with detected package manager. If repo has no `typecheck` or `test` script in package.json, omit those lines and tell the user.
+
+### 5. Create `.lintstagedrc`
+
+```json
+{
+  "*": "prettier --ignore-unknown --write"
+}
+```
+
+### 6. Create `.prettierrc` (if missing)
+
+Only create if no Prettier config exists. Use these defaults:
+
+```json
+{
+  "useTabs": false,
+  "tabWidth": 2,
+  "printWidth": 80,
+  "singleQuote": false,
+  "trailingComma": "es5",
+  "semi": true,
+  "arrowParens": "always"
+}
+```
+
+### 7. Verify
+
+- [ ] `.husky/pre-commit` exists and is executable
+- [ ] `.lintstagedrc` exists
+- [ ] `prepare` script in package.json is `"husky"`
+- [ ] `prettier` config exists
+- [ ] Run `npx lint-staged` to verify it works
+
+### 8. Commit
+
+Stage all changed/created files and commit with message: `Add pre-commit hooks (husky + lint-staged + prettier)`
+
+This will run through the new pre-commit hooks — a good smoke test that everything works.
+
+## Notes
+
+- Husky v9+ doesn't need shebangs in hook files
+- `prettier --ignore-unknown` skips files Prettier can't parse (images, etc.)
+- The pre-commit runs lint-staged first (fast, staged-only), then full typecheck and tests
