- Replace O(N*DFS) topology analyzer with O(N+E) BFS layering
- Eliminate redundant graph loads in MCP server startup
- Add bounded-concurrency parallel YAML reads in graph loader
- Add retry with exponential backoff + jitter on atomic file rename
- Migrate ad-hoc temp+rename in cross-repo-edges and repo-sentinel to atomicWriteFile
- Add topology analyzer perf test and atomic write retry unit tests
- Amend ADR-PC-0001 and ADR-PS-0001 with implementation decisions and startup NFR
- Refresh ADR manifests, indexes, rendered docs, and fixture state

Enable handbook indexing via a markdown extractor, structured workspace RECON benchmark reporting, CEM/MVC source locators (ADR-L-0020), and fix forward-depth queue explosion that caused MCP OOM on large graphs. Co-authored-by: Cursor <cursoragent@cursor.com>
Implementation decision IDs (IMPL-0001, etc.) are STE ADR artifacts, not JIRA-style ticket keys; add IMPL- to the safe prefix allowlist. Co-authored-by: Cursor <cursoragent@cursor.com>
