fix: singleton services + comprehensive test suite for MCP server

- Fix ExecutionService singleton: build_stop/get_progress/get_logs now
  share state with build_start via module-level lazy singleton
- Fix MemoryService singleton: cached Graphiti connection preserved
  across tool calls instead of re-initializing each time
- Fix MemoryService private API: use public get_relevant_context()
  instead of private _search attribute
- Add 380 tests across 12 test files covering all MCP server modules:
  config, operations, server, tasks, specs, execution, QA, workspace,
  project, ops, github, and feature tools (insights/roadmap/ideation/memory)

+### Resetting PR Review State

+To fully clear all PR review data so reviews run fresh, delete/reset these three things in `.auto-claude/github/`:
+
+1. `rm .auto-claude/github/pr/logs_*.json` — review log files
+2. `rm .auto-claude/github/pr/review_*.json` — review result files
+3. Reset `pr/index.json` to `{"reviews": [], "last_updated": null}`
+4. Reset `bot_detection_state.json` to `{"reviewed_commits": {}}` — this is the gatekeeper; without clearing it, the bot detector skips already-seen commits

+Dependency Strategy Mapping
+============================
+
+Maps dependency types to sharing strategies for worktree creation.
+
+Each dependency ecosystem has different constraints:
+
+- **node_modules**: Safe to symlink. Node's resolution algorithm follows symlinks
+  correctly, and the directory is self-contained.
+
+- **venv / .venv**: Must be recreated. Python's ``pyvenv.cfg`` discovery walks the
+  real directory hierarchy without resolving symlinks (CPython bug #106045), so a
+  symlinked venv resolves paths relative to the *target*, not the worktree.
+
+- **vendor (PHP)**: Safe to symlink. Composer's autoloader uses ``__DIR__``-relative
+  paths that resolve correctly through symlinks.
+
+- **cargo target / go modules**: Skip entirely. Rust's ``target/`` dir contains
+  per-machine build artifacts that must be rebuilt. Go uses a global module cache
+  (``$GOPATH/pkg/mod``), so there is nothing in-tree to share.
