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.

+ * #3168 — Incomplete Task→Agent dispatcher rename causes silent inline fallback.
+ *
+ * The Claude Code subagent-dispatcher tool is named `Agent`. The `Task*` namespace
+ * (TaskCreate, TaskList, TaskGet, TaskUpdate, TaskOutput, TaskStop) is the task
+ * tracker — a distinct tool set. GSD workflows were partially migrated and still
+ * reference `Task(` and `- Task` in allowed-tools/tools frontmatter in most files.
