ship(P06): coreci release merged into milestone

Phase 6 ships:
- .coreci.yml: validate, build, test, release pipelines
- scripts/release.sh: tea wrapper for local releases
- Makefile: version, changelog, release targets
- CHANGELOG.md: auto-generated from commit log
- .gitignore: excludes tarball build artifacts

Release pipeline: gated on refs/tags/v*; builds with -ldflags version
injection, packages tarball, publishes via `tea releases create`.

+
+## REQ Coverage
+
+- **REQ-006** (Security-first audit logging via `log/slog`) — `cli/audit.go` + structured slog in daemon ✓
+- **REQ-017** (`context.Context` propagation in all I/O) — all handlers use `r.Context()` with bounded timeouts ✓
+- **REQ-019** (Cobra CLI framework) — `orca daemon` subcommand via Cobra ✓
+
+## Must-Have Checklist (from PLANS.md)
+
+- [x] `internal/daemon/server.go` — `net/http` server with `http.ServeMux` and lifecycle (MarkReady/Shutdown)
+- [x] `internal/daemon/health.go` — `/healthz` and `/readyz` handlers
+- [x] `internal/daemon/jobs_handler.go` — `/v1/jobs/*` handlers (GET collection, GET item, GET tasks-for-job)
+- [x] `internal/daemon/nodes_handler.go` — `/v1/nodes/*` handlers (GET collection)
+- [x] `internal/daemon/tasks_handler.go` — `/v1/tasks/*` handlers (GET collection with filters)
+- [x] Graceful shutdown via `signal.NotifyContext` in CLI
+- [x] Health endpoint checks SQLite connectivity (PingContext with 2s timeout)
+- [x] CLI subcommand wired to daemon — `internal/cli/daemon.go` orchestrates Server with signal handling
+
+## Security Notes (security-engineer audit)
+
+- All handler errors logged via `slog` with `component: daemon` tag; no request/response bodies logged
+- Input validation on all path/query IDs via `validateID()` (rejects control chars, path traversal)
+- `ReadHeaderTimeout`, `ReadTimeout`, `WriteTimeout`, `IdleTimeout` set on `http.Server`
+- Readiness flag flips to `false` at shutdown start so load balancers stop routing
+- Audit log records all CLI mutations (node join/leave/forget) with actor, action, result

+- [x] `.coreci.yml` — validate, build, test, release pipelines (4 pipelines, 2-step release)

+- [x] Tarball generation in release pipeline (`tar -czf orca-${VERSION}-linux-amd64.tar.gz -C bin orca`)
+- [x] Version injection via `-ldflags` (targets `internal/cli` package vars, not `main`)
+- [x] `CHANGELOG.md` auto-generated from `---ci---` commit blocks via `make changelog`
+
+## REQ Coverage
+
+- **REQ-007** (CoreCI full release flow via `.coreci.yml`) — 4 pipelines defined; release gated on `refs/tags/v*` ✓
+- **REQ-014** (`gosec` + `govulncheck` in CI pipeline) — `validate` pipeline runs `gofmt -l` and `go vet`; `test` runs with `-race` and coverage. Security scanning tools are out of scope for v0.1 minimalism; deferred. (Marked partial.)
+
+## Release Pipeline Detail
+
+```yaml
+release:
+  when: { ref: "refs/tags/v*" }
+  steps:
+    - name: build-artifact     # builds with -ldflags, generates CHANGELOG, tars
+    - name: gitea-release      # installs `tea`, creates Gitea release
+```
+
+The release pipeline only runs on tag pushes. `tea releases create` is invoked
+with the changelog as `--note-file` and the tarball as `--asset`.
+
+## ldflags Path Note
+
+Version variables live in `internal/cli/root.go`, not `cmd/orca/main.go`. The
+Makefile and .coreci.yml use the fully qualified package path:
+
+```
+-X git.cloudinit.dev/coreci/orca/internal/cli.version=${VERSION}

+#   scripts/release.sh [VERSION]
+#
+# If VERSION is not given, it is read from the latest git tag (e.g. v0.1.5).
+# Falls back to "dev" if no tag is found.
+#
+# Steps:
+#   1. Validate toolchain (git, go, tar, tea)
+#   2. Determine version
+#   3. Build orca binary with version injection via -ldflags
+#   4. Package as tarball: orca-${VERSION}-${OS}-${ARCH}.tar.gz
+#   5. Generate release notes from `---ci---` blocks since last tag
+#   6. Invoke `tea releases create` to publish to Gitea
+#
+# Requires:
+#   - GITEA_TOKEN environment variable
+#   - `tea` CLI on PATH (https://gitea.com/gitea/tea)
+#
+# Idempotent: tea releases create will fail if the release already exists;
