WP-0001 complete: v1.1.0 lazy registry and install performance

Lazy-load agent registry (frontmatter index, parse on demand), copy
agents by path during install, fix Makefile template tab lint issue,
add registry performance tests, bump to 1.1.0, document CLI reinstall
after pull.

 ## [Unreleased]
 
+## [1.1.0] - 2026-06-18
+
 ### Added
-- **sys-medic agent**: Linux/Kubernetes node health assessment agent integrated as a standard kaizen-agentic infrastructure agent (KAIZEN-WP-0002 Part 1)
-- **Ecosystem integration (WP-0004)**: Helix Forge correlation (`metrics correlate`, `HELIX_SESSION_UID` env), artifact-store publish (`metrics publish`), activity-core ActivityDefinition references, integration patterns docs
-- **Community engagement (WP-0001 partial)**: `kaizen-agentic feedback` CLI, Gitea issue templates, `.gitea/workflows/ci.yml`, `.pre-commit-config.yaml`, `docs/FEEDBACK.md`, `docs/TELEMETRY.md`
-- **Project metrics convention (ADR-004)**: `.kaizen/metrics/<agent>/` storage via `MetricsStore` and `OptimizerStore`
-- **Metrics CLI**: `kaizen-agentic metrics record|show|list|export|optimize` for per-execution records and optimizer analysis
-- **Optimizer integration**: `OptimizationLoop.from_metrics_store()` wired to project metrics; `memory brief` includes `## Performance Summary`
-- **tdd-workflow metrics pilot**: Reference agent for measure → analyse → orient loop (`wiki/AboutKaizenAgents.md`)
-- **Packaged agents**: `coach`, `sys-medic`, `scope-analyst`, and `optimization` synced to `src/kaizen_agentic/data/agents/` (20 agents total)
+- **`kaizen-agentic feedback`** CLI and Gitea issue templates for developer feedback
+- **Gitea CI** (`.gitea/workflows/ci.yml`) — black + pytest on Python 3.10/3.12
+- **Pre-commit hooks** (`.pre-commit-config.yaml`) and `make pre-commit-install`
+- **`docs/FEEDBACK.md`** and **`docs/TELEMETRY.md`** (ADR-004 two-layer telemetry model)
+- **Ecosystem integration (WP-0004)**: Helix correlation, artifact-store publish, activity-core definitions
+- **Project metrics (WP-0003)**: ADR-004 storage, metrics CLI, optimizer wiring, tdd-workflow pilot
+- **sys-medic agent** and packaged fleet sync (20 agents in `data/agents/`)
+
+### Changed
+- **Lazy agent registry** — index by frontmatter name; parse on demand; path-based install copy
+- **CLI error messages** — clearer guidance when agents directory or package missing
+- **CONTRIBUTING.md** — post-pull reinstall instructions (`pip install -e .` / pipx)
+
+### Fixed
+- **Makefile template** in project initializer — tab characters no longer break Python linting
+- Removed stale `agents_backup_*/` scaffolding from development installs
