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

+
+# TanStack Integration Best Practices
+
+Guidelines for integrating TanStack Query, Router, and Start together effectively. These patterns ensure optimal data flow, caching coordination, and type safety across the stack.
+
+## When to Apply
+
+- Setting up a new TanStack Start project
+- Integrating TanStack Query with TanStack Router
+- Configuring SSR with query hydration
+- Coordinating caching between router and query
+- Setting up type-safe data fetching patterns
+
+## Rule Categories by Priority
+
+| Priority | Category | Rules | Impact |
+|----------|----------|-------|--------|
+| CRITICAL | Setup | 3 rules | Foundational configuration |
+| CRITICAL | SSR Integration | 1 rule | Router + Query SSR setup |
+| HIGH | Data Flow | 4 rules | Correct data fetching patterns |
+| MEDIUM | Caching | 3 rules | Performance optimization |
+| MEDIUM | SSR | 2 rules | Additional SSR patterns |
+
+## Quick Reference
+
+### Setup (Prefix: `setup-`)
+
+- `setup-query-client-context` — Pass QueryClient through router context
+- `setup-provider-wrapping` — Correctly wrap with QueryClientProvider
+- `setup-stale-time-coordination` — Coordinate staleTime between router and query
+
+### Data Flow (Prefix: `flow-`)
+
+- `flow-loader-query-pattern` — Use loaders with ensureQueryData
+- `flow-suspense-query-component` — Use useSuspenseQuery in components
+- `flow-mutations-invalidation` — Coordinate mutations with query invalidation
+- `flow-server-functions-queries` — Use server functions for query functions
+
+### Caching (Prefix: `cache-`)
+
+- `cache-single-source` — Let TanStack Query manage caching
+- `cache-preload-coordination` — Coordinate preloading between router and query
+- `cache-invalidation-patterns` — Unified invalidation patterns
+
+### SSR Integration (Prefix: `ssr-`)
+
+- `ssr-dehydrate-hydrate` — Use setupRouterSsrQueryIntegration for automatic SSR
+
+### Additional SSR (Prefix: `ssr-`)
+
+- `ssr-per-request-client` — Create QueryClient per request
+- `ssr-streaming-queries` — Handle streaming with queries
+
+## How to Use
+
+Each rule file in the `rules/` directory contains:
+1. **Explanation** — Why this pattern matters
+2. **Bad Example** — Anti-pattern to avoid
+3. **Good Example** — Recommended implementation
+4. **Context** — When to apply or skip this rule
