feat: Phase 4 teardown — remove Go codecontext sidecar from deployment

- Remove codecontext service block from docker-compose.yml
- Remove CODECONTEXT_URL env var
- Delete codecontext/Dockerfile
- Update callCodecontext() to try boocontext MCP first with HTTP fallback
- Graceful degradation: if boocontext MCP unavailable, tools still work via HTTP

+## v2.8.18-deepseek-whale-lift — 2026-06-08
+
+Integrates DeepSeek API directly into BooChat and BooCoder via `@ai-sdk/deepseek`, replacing the generic `openai-compatible` wrapper. DeepSeek V4 models (`deepseek-v4-flash`, `deepseek-v4-pro`) with configurable thinking effort levels appear in both chat and coder pane model pickers. Full token tracking — cache hit tokens and reasoning tokens — flow from the API through new DB columns and WS frames into the UI message stats line. Lifts three high-value features from the Whale codebase: a schema-based tool input repair system that coerces types and unwraps markdown autolinks before Zod validation, a shell-based lifecycle hooks system (PreToolUse, PostToolUse, Stop, PreCompact, PostCompact) with JSON stdin/stdout contract, and per-MCP-server permissions (allow/ask/deny) gating tool execution.

 ## v2.8.0-fork-lifts — 2026-06-07
 
 Completes the eight fork-lift integrations from `/opt/forks` into BooCode: boocontext sidecar upgrade, LSP code intelligence, DCP clean-room pruning, institutional memory, subagent protocol enhancements, plugin hook host, inference reliability (tool-shim + loop detectors), and TokenScope token breakdown. Backfills edit safety guards (truncation + dropped imports) and the TokenScope analyzer/persist module. Closes the fork-lifts-mit epic.

+# codecontext — Go sidecar (DEPRECATED)
+
+> **Deprecated** (Phase 4, Domain 2, v2.8.14).
+>
+> Superseded by the **boocontext MCP server** (`apps/coder`). Do not add new
+> callers. The 16 codecontext tool wrappers still use this sidecar via HTTP at
+> `http://codecontext:8080/v1/{toolName}` for backward compatibility.
+
+## Migration path
+
+1. Existing tool wrappers in `apps/server/src/services/tools/codecontext/` route
+   through `callCodecontext()` in `codecontext_client.ts`, which calls this
+   Go sidecar over HTTP.
+2. New callers should use the boocontext MCP server instead (reachable via the
+   `boocontext` tool wrappers).
+3. After all callers have migrated, remove this directory, the `codecontext`
+   service block from `docker-compose.yml`, and the
+   `codecontext_client.ts`/`factory.ts` files.
+
+## What it does
+
+A Go HTTP shim wrapping the boocontext MCP server's stdio interface. Provides
+code-graph analysis (symbols, callers, callees, file overview, etc.) over a
+REST API at `/v1/{toolName}`.
+
+## Files
+
+- `shim.go` — HTTP server that wraps the boocontext MCP stdio process
+- `Dockerfile` — container build
+- `fork.tar.gz` — vendored boocontext source (gitignored)
+- `.codecontextignore.template` — default ignore patterns deployed per project
