Step 263: saveBuffer/saveAllBuffers RPC methods write editBuf to disk with
workspace path resolution and parent dir creation. 12/12 tests.
Step 264: State-based undo/redo via HeadlessUndoStack. Snapshots recorded
automatically before mutations; undo/redo restore AST + editBuf. 12/12 tests.
Step 265: Phase 9e integration tests — save after undo/redo, mixed undo
states across buffers, full open→mutate→diagnose→undo→redo→save. 8/8 tests.
Phase 9e complete: 32/32 tests. Sprint 9 total: 244/244 across 5 phases.
34 MCP tools.

Adds multi-buffer management via openFile/closeFile/listBuffers/setActiveBuffer
RPC methods, plus indexWorkspace for scanning workspace files without opening
them. Language auto-detected from extension. 27 MCP tools total (was 22).

Optional budget parameter on getAST and getDiagnostics. Responses exceeding
the budget are truncated with continuation tokens for paginated follow-up.
Binary search finds max array elements fitting the budget. Diagnostics sorted
by severity (errors first) before truncation.

DiagnosticVersionTracker records snapshots and computes added/removed deltas
between versions. Agents can efficiently check if their fix resolved an error
without re-fetching all diagnostics. 21 MCP tools total.

Adds token-efficient AST queries: compact mode (<30% of full size),
subtree extraction by nodeId, version-tracked AST diff after mutations,
and tokenEstimate on all responses. 12/12 tests pass, 17 tools total.

Adds 5 workspace-aware file I/O tools to the MCP server so agents can
manage files without a GUI. All paths are resolved against --workspace
root with escape-rejection security. 12/12 tests pass, tool count now 15.

Adds the headless agent architecture for Sprint 9 Phase 9a:
- ASTUtils.h: pure AST utilities extracted from EditorUtils.h
- HeadlessEditorState.h: GUI-free state with buffer management
- HeadlessAgentRPCHandler.h: full RPC dispatch (20+ methods)
- step245_test.cpp: 20 tests all passing
Also fixes test compilation errors (NotificationSystem API changes,
AgentRole permissions, DependencyPanel missing include) and adds
SDL2 system library detection fix in CMakeLists.txt.
