* test: ratchet mutation score over enumerated decision kernels
Adds a Stryker (vitest runner) mutation lane scoped to the decision kernels,
a per-module baseline with tool/config provenance, and a ratchet that only
lets scores rise. Non-gating until two consecutive stable weekly sweeps.

* test: own kernel tests in the mutation registry and ship the #1430 lane envelope
- restore bench:help-conformance, broken by a formatting-path edit
- kernel test files select their module on PRs (registry `tests` + workflow paths),
asserted to reach the kernel through the import graph
- every mutation run writes the standard scheduled-lane artifact envelope
- move src/utils/__tests__/errors.test.ts beside its source per the mirror rule

* test: derive kernel test ownership and land the scheduled-lane health monitor
Ownership of a kernel's tests is now computed from the static import graph
(scripts/mutation/ownership.ts) instead of a hand-listed set, so a test that
reaches a kernel indirectly -- src/__tests__/daemon-error.test.ts through
src/daemon.ts -- selects that kernel on a PR. The PR lane triggers on every src
test and shards the derived modules, keeping wall clock at one module.
The lane envelope (#1430) is now written on every exit path with the stage it
reached, so a crash before any mutant runs is distinguishable from a lane that
never ran. Adds the derived cadence monitor (scripts/lane-health, daily
workflow): scheduled lanes are enumerated from .github/workflows/ and reported
dark, failing, or never-run against their own cron cadence.
* fix: merge only Stryker reports from a shard directory
The shard artifacts now carry the lane envelope beside mutation.json, and the
merge globbed every .json under the download path, so the ratchet job fed the
envelope to the report parser and died after the mutants had already run.
* fix(mutation): fail on incomplete shard sets and envelope pre-run failures
