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.

+## Tool reliability
+- `edit_file`'s fuzzy match can **succeed on a near-miss** or **return ambiguous** when `old_string` matches multiple locations. Always verify the queued diff before calling `apply_pending` — the diff preview is authoritative, the tool's "success" return is not.
+- The external agent's worktree diff only shows changes since the **last turn**, not since the project baseline. The DiffPanel merges these, but if you call `git diff` directly, you'll get incomplete results.

 ## Pending changes discipline
 
 Every file modification queues in `pending_changes` before touching disk. The user sees a diff preview and approves/rejects each change. Never bypass this queue — it is the safety boundary between inference and the filesystem.

+## 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.
+
+## v2.8.19-paseo-orchestrator-ph1-2 — 2026-06-08
+
+Ships the trace system and session persistence backbone. Every tool call is now timed via `tool_traces` DB table with latency, token counts, cache/reasoning breakdowns, and WS frames streamed live to a new trace viewer pane. Agent sessions survive browser refresh — `agent_snapshots` table persists state on turn boundaries and restores on WebSocket reconnect. A session timeline view shows agent turn history with scroll-to and restore. New frontend components: `TraceViewer` (collapsible panel with timing bars) and `SessionTimeline` (vertical timeline).
+
 ## 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.

+- Do NOT remove the abort-signal pinning comment in `stream-phase.ts` — `fullStream` exits cleanly on abort without throwing; the post-iteration `if (signal?.aborted)` check is the only thing that distinguishes cancelled from complete.
+- Do NOT remove `includeUsage: true` from `provider.ts` — the adapter defaults it false; without it, token counts are always NULL.
+- Do NOT add raw `broker.publish()`/`publishUser()` calls — always use `publishFrame`/`publishUserFrame` which Zod-validate against `WsFrameSchema`.

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.

 3. Any project documentation found in the repo root (BOOCHAT.md, AGENTS.md, roadmap docs, CONTEXT.md).
 
 Rules:
 - Cite specific files and line numbers when making claims about code.
 - If project docs contradict the code, docs win for questions about state, version, status, or roadmap. Code wins for questions about runtime behavior or implementation.
-- If the codecontext output looks sparse (low symbol count for a TypeScript project, missing dependency edges, empty framework list), explicitly say so — codecontext falls back to the JavaScript grammar for TypeScript and loses interfaces, generics, decorators, and type aliases.

 - Do not invent symbols, files, or relationships that are not present in the inputs.
 - 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.
