feat(harness): P1 — single registry-backed meta loader (rcust)
One loader: runner/harness/meta.py::load(recipe) -> RecipeMeta (frozen dataclass,
attribute access), backed by the declarative KEYS registry (14 final keys + 3
P2-deprecated). The ONLY exec() of tests/<recipe>/recipe_meta.py. Validation per
the locked decision: unknown ALL-CAPS top-level name or type mismatch = MetaError
(hard error at load); underscore-prefixed names recipe-private; callables only on
hook-typed keys.

Migrated all six legacy loaders (spec §4 L1–L6):
- run_recipe_ci.py::_load_meta deleted; orchestrator loads once, passes meta down
- tests/conftest.py::_recipe_meta deleted; meta fixture returns full RecipeMeta (R3)
- lifecycle.py::_recipe_extra_env/_recipe_meta_flag deleted; deploy_app takes meta
- deps.py::declared_deps deleted; callers read meta.DEPS
- canonical.py::is_enrolled reads through meta.load()
- screenshot.py now actually receives SCREENSHOT through the orchestrator path (R2
  fix; proven by unit test through the real load path)

Mumble private constants underscore-prefixed (_WELCOME_TEXT_MARKER/_MAX_USERS) +
importers fixed. New tests/unit/test_meta.py (all-recipes-load-clean typo gate,
MetaError cases, spec §2 baseline defaults, underscore exemption, doc sync). Docs
§4 key table now GENERATED from the registry (scripts/gen-meta-docs.py); drift
fails CI.

Verified on cc-ci: cc-ci-run -m pytest tests/unit -q -> 175 passed; scripts/lint.sh -> PASS.

"""Render the harness.meta KEYS registry to the markdown key-reference table in
docs/recipe-customization.md §4 (rcust P1.5; kills the R5 doc-drift class).
Usage:
python3 scripts/gen-meta-docs.py # rewrite the table in-place between the markers
python3 scripts/gen-meta-docs.py --print # print the rendered table to stdout (used by the
# doc-sync unit test, tests/unit/test_meta.py)
The table lives between `<!-- META-TABLE-START -->` / `<!-- META-TABLE-END -->` markers; a unit
test asserts the committed table equals this rendering, so editing it by hand fails CI.
