### Added

- Documented `PROJECT_REGISTRY` in `README.md` and `DOCKER_README.md` to formally support Multi-Project Workspaces.
- Added "Dynamic Context Resolution & Auto-Detection" section detailing the multi-project routing behavior to READMEs.
- Added `get_github_context` support for explicit `owner` and `repo` arguments, enabling dynamic physical directory mounting via `PROJECT_REGISTRY`.
- Added dynamically resolved `memory://briefing/{repo}` resource to allow explicit repo selection when multiple projects are registered.
- Created `session-summary` workflow prompt documentation focusing on `team-session-summary` cross-session handoff patterns.
- Expanded the E2E verification suite (`integration-workflows.spec.ts`) to validate multi-project context resolution capabilities under high-load.

### Changed

- Enhanced `github-section` context builder to dynamically resolve context targets utilizing `PROJECT_REGISTRY`.
- Updated documentation resource counts in README/DOCKER_README to `33` to reflect template expansion via dynamic `{repo}` params.
- Handlers mapped to GitHub API paths now perform contextual lookups matching explicit `repo` params against `PROJECT_REGISTRY` before attempting git-cli operations.

### Fixed

- Fixed `memory://briefing` returning stale context when `PROJECT_REGISTRY` was enabled without a fallback default repo.
- Fixed `issueUrl` tracking anomaly where the URL field incorrectly populated from the PR branch API instead of the Issue API during combined operations.
- Resolved Zod boundary exceptions in `create_github_milestone` resulting from malformed ISO date coercions when parsing incomplete markdown strings.
- Fixed raw MCP `-32602` errors leaking through `update_entry` validation layers when encountering unexpectedly long `description` strings.
- Fixed `get_kanban_board` column mapping failure caused by legacy `status` string mismatches when retrieving v2 boards.
