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

+# C3 Usage Patterns
+
+## Quick Workflows
+
+```bash
+# TypeScript API Worker
+npm create cloudflare@latest my-api -- --type=hello-world --lang=ts --deploy
+
+# Next.js on Pages
+npm create cloudflare@latest my-app -- --type=web-app --framework=next --platform=pages --ts --deploy
+
+# Astro static site  
+npm create cloudflare@latest my-blog -- --type=web-app --framework=astro --platform=pages --ts
+```
+
+## CI/CD (GitHub Actions)
+
+```yaml
+- name: Deploy
+  run: npm run deploy
+  env:
+    CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
+    CLOUDFLARE_ACCOUNT_ID: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
+```
+
+**Non-interactive requires:**
+```bash
+--type=<value>       # Required
+--no-git             # Recommended (CI already in git)
+--no-deploy          # Deploy separately with secrets
+--framework=<value>  # For web-app
+--ts / --no-ts       # Required
+```
+
+## Monorepo
+
+C3 detects workspace config (`package.json` workspaces or `pnpm-workspace.yaml`).
+
+```bash
+cd packages/
+npm create cloudflare@latest my-worker -- --type=hello-world --lang=ts --no-deploy
+```
+
+## Custom Templates
+
+```bash
+# GitHub repo
+npm create cloudflare@latest -- --template=username/repo
+npm create cloudflare@latest -- --template=cloudflare/templates/worker-openapi
+
+# Local path
+npm create cloudflare@latest my-app -- --template=../my-template
+```
+
+**Template requires `c3.config.json`:**
+```json
+{
+  "name": "my-template",
+  "category": "hello-world",
+  "copies": [{ "path": "src/" }, { "path": "wrangler.jsonc" }],
+  "transforms": [{ "path": "package.json", "jsonc": { "name": "{{projectName}}" }}]
+}
+```
+
+## Existing Projects
+
+```bash
+# Add Cloudflare to existing Worker
+npm create cloudflare@latest . -- --type=pre-existing --existing-script=./dist/index.js
+
+# Add to existing framework app
+npm create cloudflare@latest . -- --type=web-app --framework=next --platform=pages --ts
+```
+
+## Post-Creation Checklist
+
+1. Review `wrangler.jsonc` - set `compatibility_date`, verify `name`
+2. Create bindings: `wrangler kv namespace create`, `wrangler d1 create`, `wrangler r2 bucket create`
+3. Generate types: `npm run cf-typegen`
+4. Test: `npm run dev`
+5. Deploy: `npm run deploy`
+6. Set secrets: `wrangler secret put SECRET_NAME`
