M6 (part 1): per-recipe meta + D4 recipe-local discovery + shared naming helper

Recipe-agnostic harness (no surgery to enroll a recipe): recipe_meta.py for
health path/codes/timeouts; run_recipe_local discovers + runs recipe-shipped
tests/ against the live app. install non-regressed.

+## 2026-05-27 — M6 (part 1): harness enhancements for recipe #2 + D4 discovery
+
+Before enrolling recipe #2, made the shared harness recipe-agnostic so enrolling a recipe needs no
+harness-code change (D5):
+- **Per-recipe meta** (`tests/<recipe>/recipe_meta.py`, optional): HEALTH_PATH, HEALTH_OK,
+  DEPLOY_TIMEOUT, HTTP_TIMEOUT. conftest reads it; `wait_healthy` gained a `path` param (e.g.
+  keycloak `/realms/master`). Defaults preserve custom-html behaviour (verified: install still green).
+- **Shared naming** (`harness/naming.py`): single source for the `<recipe[:4]>-<6hex>` domain, used
+  by conftest + the orchestrator.
+- **D4 recipe-local discovery** (`run_recipe_ci.run_recipe_local`): if a recipe ships `tests/` with
+  `test_*.py`, deploy the app, run those tests against the LIVE deployment (contract: env
+  `CCCI_BASE_URL` + `CCCI_APP_DOMAIN`), merge as another reported stage, guaranteed teardown. Real
+  recipes ship tests/ committed in their repo (clean checkout) → discovered on clone/fetch. (custom-
+  html via catalogue is an awkward case — abra refuses an unstaged recipe and `abra recipe fetch`
+  resets local commits — so D4 is demonstrated end-to-end with recipe #2 hedgedoc, which ships
+  committed tests/.)
+
+**Next:** mirror hedgedoc (postgres+hedgedoc, DB-backed) via the mirror+PR flow with a committed
+tests/ dir, write tests/hedgedoc/ (install/upgrade/backup + recipe_meta), run all stages + D4 green.
