test(#1972): consolidate 94 command/module regression tests into subject suites

Fold 94 issue-named command/module regression files into the canonical test file
that owns each subject-under-test, across 52 existing suites (state, config, frontmatter,
roadmap-parser, capability-registry, shell-command-projection-dispatch, plan-phase-drift-guard,
health-validation, runtime-converters, commands, etc.). Verbatim block-scoped describe
wrappers; 881 subtests conserved 1:1. No new test files.

Host-env pre-check (per B2): the only GSD_WORKSTREAM/GSD_PROJECT-touching destinations
(intel, planning-workspace) clear those vars hermetically, so folded CLI tests are safe.

Regenerates regression-name allowlist (222->162), ratchets file-count allowlist across
8 buckets (validate entry removed after dropping <=2), makes 34 relocated allow-test-rule
exemptions issue-ref-compliant (ADR-456; prunes 34 stale ids). Repoints CONTEXT.md +
ADR-0002/443/1235/3524 test-file references. lint:ci green.

Part of epic #1969. Closes #1972.

 Before this ADR, the command contract was enforced inconsistently:
 - `tests/enh-2790-skill-consolidation.test.cjs` checked existence and frontmatter of specific post-consolidation commands
-- `tests/bug-3135-capture-backlog-workflow.test.cjs` checked `execution_context` @-ref resolution (added 2026-05-05)
+- `tests/docs-update.test.cjs` (folds former `bug-3135-capture-backlog-workflow`, consolidation epic #1969) checked `execution_context` @-ref resolution (added 2026-05-05)
 - No test checked `allowed-tools` validity, `name:` convention, or `description:` non-emptiness across all commands simultaneously
 
 This meant any PR touching a command file could break the contract without a single test catching it. The `add-backlog.md` gap (#3135) is a concrete example: the workflow file was missing for the full consolidation cycle before a targeted regression test was written.

 Agent installation is the last major artifact class in `install()` that does **not** flow through the descriptor-driven path established by ADR-3660 (`installRuntimeArtifacts` → `_copyStaged`, with each runtime's artifacts declared in the capability registry's `artifactLayout`). Skills and kimi-agents already flow through it. The claude-**local** `agents` kind is *declared* in the descriptor (raw-copy, `converter: null`), but production `install()` still produces claude-local agent output via the inline loop — the skills-runtime gate routes Claude through `installRuntimeArtifacts` only when `isGlobal` (`bin/install.js` ~9822/9829), and claude-local commands/agents go through the back-compat copy path. So agents for **every** runtime (claude included) are, in practice, converted and written by a **separate inline loop** in `bin/install.js` (currently lines ~10102–10249).
 
-This was surfaced while attempting #1173: #1227 added the `convertedAgentsKind` plumbing to the layout module, but it is **inert in production** — no runtime descriptor declares an `agents` kind with a non-null `converter`, so `dispatchKindEntry` always routes to the raw-copy `agentsKind`. The plumbing is exercised only by `tests/feat-1173-agent-converters-descriptor.test.cjs` against a synthetic registry.

 A naive cutover (point descriptors at the extracted converters, delete the inline loop) **regresses installs for every runtime**, because the inline loop performs cross-cutting and runtime-specific pipeline steps that the descriptor agents path does not replicate, and because the extracted converters' signature cannot receive the context those steps require. Two of those behaviors have no converter function at all today. Because the migration touches install correctness across ~15 runtimes in the most-edited install module, the cutover strategy and the parity-test contract are architectural decisions worth recording before code.
