feat: remove Go codecontext sidecar, wire all boocontext MCP tools

Deletes all 17 native codecontext tool wrappers (~2,400 lines). Code analysis now provided entirely by boocontext MCP server (discovered at startup via appendMcpTools()). Adds 9 previously missing MCP tools (get_summary, scan, get_coverage, get_schema, get_env, get_events, get_knowledge, get_wiki_index, lint_wiki) to all relevant agent tool lists. Updates AGENTS.md, guidance files.

 ## v2.8.25-codecontext-removal — 2026-06-08
 Removes all remaining Go codecontext sidecar references. The 17 native codecontext tool wrappers (`get_codebase_overview`, `search_symbols`, `get_blast_radius` etc.) have been deleted from the source tree. Code analysis tools are now provided entirely by the boocontext MCP server, discovered at startup via `appendMcpTools()`. All 9 previously unavailable boocontext MCP tools (`get_summary`, `scan`, `get_coverage`, `get_schema`, `get_env`, `get_events`, `get_knowledge`, `get_wiki_index`, `lint_wiki`) are now wired into every relevant agent's tool list in `data/AGENTS.md`. Guidance files (`CLAUDE.md`, `BOOCHAT.md`) updated accordingly. 22 files deleted (~2,400 lines removed).
 ## v2.8.20-paseo-orchestrator-ph3-5 — 2026-06-08
 Completes the Paseo-like Orchestrator with phases 3–5. Phase 3 ships a Dynamic Workflow Engine built on Node's `vm` sandbox — Claude Code compatible JavaScript workflows with `agent()`, `parallel()`, `pipeline()`, `phase()`, and `budget()` primitives. Includes a built-in workflow catalog (`deep-research`, `review-code`, `find-issues`) with SHA-256 hash-based resumability cache that skips completed steps on re-run. Phase 4 adds background subagents — `spawn_subagent` returns immediately, `subagent_status` and `subagent_result` tools let the model poll and collect results. Phase 5 adds a cache shape telemetry badge to the trace viewer (colored bar + hit rate percentage) and a multi-modal attachment stub. Also ships inline diff snippets in the chat stream after write tool calls, and the `run_command` tool with auto-fix loop that detects build failures after edits and injects errors for self-correction.

 - `/opt/boolab` hosts a sibling BooCode at `boocode.indifferentketchup.com` — useful for side-by-side iPhone comparison when debugging booterm rendering. It uses Tailwind v3, boocode uses v4 — don't assume build parity.
 - booterm SSHs to the host as `samkintop@100.114.205.53` (the Tailscale IP). The hostname `ubuntu-homelab` (in the bash prompt) does NOT resolve inside the container. Override via `BOOTERM_SSH_HOST` / `BOOTERM_SSH_USER` env vars in docker-compose if the shell moves to a different machine.
- codecontext sidecar lives at `/opt/boocode/codecontext/`. HTTP API at `http://codecontext:8080/v1/<tool_name>` over the `boocode_net` bridge (no host port). BooCode wrappers in `apps/server/src/services/tools/codecontext/`. The `.codecontextignore` at project root is honored when `--respect-gitignore` is passed (enabled in the shim).
+- Boocontext MCP server integrates tree-sitter code analysis tools (callgraph, health, impact, symbols, types, wiki). Wrappers in `apps/server/src/services/tools/codecontext/` (directory name retained for import compat). Invoke boocontext tools through the tool registry — MCP tools are appended at startup via `appendMcpTools`.
- codecontext fork at `/opt/forks/codecontext/` — separate git repo (branch `boocode-ts`), pushed via the boocode_gitea SSH key to `indifferentketchup/codecontext`. Build `go build ./...`; test `go test ./...`. Docker rebuild requires staging the fork first: `tar -czf codecontext/fork.tar.gz -C /opt/forks/codecontext --exclude=.git --exclude=bin .` then `docker compose build --no-cache codecontext` (the Dockerfile COPYs `fork.tar.gz` into the builder stage; Gitea is behind Authelia, no HTTP clone). `fork.tar.gz` is gitignored.
+- The old Go codecontext sidecar has been removed from the Docker deployment (v2.8.20). The TypeScript boocontext fork at `/opt/forks/codecontext/` (branch `boocode-ts`) still exists for reference but is no longer deployed. Build: `go build ./...` from within that directory if needed for local testing.

 - Tool-name whitelists must derive from `ALL_TOOLS` in `services/tools.ts`, never hardcoded (this drift class hit `services/agents.ts` `ALL_TOOL_NAMES` before).
 - Agent registry lives at `data/AGENTS.md` (global, bind-mounted at `/data/AGENTS.md`). No per-project `AGENTS.md` in this repo (removed to eliminate two-files-must-stay-in-sync drift); the `getAgentsForProject` per-project override mechanism remains for *other* projects.
 - `data/AGENTS.md` is PARSED (`agents.ts` `splitSections`/`parseAgentSection`): each `## <Name>` is one agent and must be followed by a `---` frontmatter fence or the block throws; content before the first `## ` is discarded. Do NOT add free-form `## ` rule sections — they break the registry. Cross-cutting agent rules go in CLAUDE.md or a parser-ignored preamble.

 - **`payload.ts:loadContext` SELECT** must include every `Session` field downstream code reads. The tool phase reads `session.allowed_read_paths`; if the SELECT omits it, cross-repo read grants silently fail. `sql<Session[]>` doesn't enforce column coverage, so the type doesn't catch it.
 - **Sidecar routing** (`services/inference/provider.ts`): `upstreamModel(config, modelId, agent)` routes to `LLAMA_SIDECAR_URL` when the agent has `llama_extra_args`, else `LLAMA_SWAP_URL`. `resolveRoute(agent)` returns `{route, flags}`. Sidecar provider created fresh per call (not cached) because `X-Agent-Flags` varies per agent. Boot-time guard in `index.ts` refuses to start if any agent has `llama_extra_args` but `LLAMA_SIDECAR_URL` is unset.
 - **Secret guard safe patterns** (`services/secret_guard.ts`): `.env.example`, `.env.sample`, `.env.template`, `.env.defaults` are allowlisted via `SAFE_PATTERNS`. Do NOT add `.env.production`/`.env.development`/`.env.test` — those can hold real secrets.

 // DEPRECATED (Phase 4, Domain 2, v2.8.14): This HTTP client routes through

 //
 //   1. target_dir validation. Codecontext's HTTP shim is naive and forwards
 //      any target_dir to codecontext, so without this layer a model that
 //      hallucinated a target_dir could read /opt/anything-on-disk. The
 //      project root is realpath'd and the requested target_dir is constrained
 //      to it (same invariant as path_guard.ts but for the codecontext path).

 //      that can balloon on large projects; the model can re-narrow via
 //      file_path / file_type / limit. Matches the "inline truncation, no
 //      opaque-id retrieval" decision locked in the 2026-05-21 recon.
 //   3. Friendly mapping of codecontext's known failure modes — the empty-
 //      file parser bug (upstream issue #37) returns a generic error string,
 //      which we re-surface with a hint to add the file to .codecontextignore.

 - Do not respond with a generic "this looks like a [framework] project" summary. The user has the framework analysis already. Add specifics: what is actually in this codebase, what is shipped, what is planned, what is load-bearing.
 - Length: match the depth the user asked for. Overview questions get structured multi-section answers. Specific questions get focused answers.

 description: Implements changes using read and write tools. Routes all writes through pending changes.

 You implement. Read the code, make the changes, verify they work.
 Process:
 1. Read the target files and understand the current state.
-2. Use grep and get_dependencies to find all call sites and dependents.
+2. Use grep and boocontext_boocontext_callgraph to find all call sites and dependents.
 3. Make changes via edit_file / create_file. All writes queue in pending_changes.
 4. Review pending changes before calling apply_pending.
 5. After applying, verify: read the modified files, check that the change is correct.
