* ci: backport scoped heavy CI to narthex Backport #9927 and the CI-only changes from #10043. Adapt script references to narthex, preserve manual platform checks, and document the default-branch schedule limitation.

Heavy CI scheduling
Checks, Rust CI, and Integration CI each run the shared GitHub script test action before expensive builds and tests. A failed, skipped, or cancelled script-test job blocks those jobs, including manually dispatched runs. Each workflow runs its own preflight so it does not wait on another workflow run.
Rust CI runs Windows and RISC-V compilation checks only on schedule or manual dispatch, not on PRs or merge groups. Windows nextest and Windows SQLness run in the existing Nightly CI workflow, which also supports manual dispatch. Its existing schedule is Tuesday through Friday at 07:00 Asia/Shanghai, not every day. No new Windows test job is added.
Integration CI admits fuzz when a non-draft PR is opened or marked ready for review, selecting suites with the existing diff-scope classifier. Its weekday schedule (23:00 Asia/Shanghai, Monday through Friday) runs all fuzz suites. Ordinary pushes and reopening do not run fuzz; core integration checks still run. Merge groups continue to skip fuzz.
Re-running an ordinary push-triggered Integration CI run does not enable fuzz. A new push can cancel an earlier ready-for-review run. Use an explicit fuzz profile through the CI entry points below when later changes need fuzz coverage.
For a same-repository branch, use Run workflow and select fuzz_profile
(standalone, distributed, chaos, or all). The default none runs core
integration without fuzz. The existing /ci fuzz ... commands remain available
for same-repository draft PRs with their existing authorization rules.
Validate job admission with node --test .github/scripts/heavy-ci-policy.test.cjs.
These tests verify triggering decisions, not runner availability or performance.
Narthex branch
GitHub schedules run only on the default branch. They do not test narthex
automatically. To validate this branch, manually dispatch Rust CI, Integration
CI (selecting a fuzz profile), or Nightly CI with narthex as the ref.
Land these scope rules on narthex before updating dependent PR branches:
the classifier checks out the PR base revision, not the PR head.
