v14.0.1

Patch release. v14.0.0 was the intended Phase DE cut but release CI
caught a hardcoded test assertion (test_run_postgres_config_smoke
asserted the operator's local deployment_name="qsgen-postgres"; the
CI workflow rewrites run/config.postgres.yaml with a per-run
qs-ci-<run-id>-pg value before tests fire — POLICY 1 divergence).
The over-specified assertion was dropped; the dialect check (which
survives CI's overwrite) remains. No runtime behavior change vs
v14.0.0; pip-install v14.0.1 to skip the broken-release-attempt tag.

Paired into this cut: README v14 cfg-shape callout + chain layer
string + triage verb; docs/specs/SPEC_studio.md field names; Phase
DE swept to PLAN_ARCHIVE.md.
