test(#1973): consolidate 48 workflow regression tests into workflow-aspect suites

Fold 48 issue-named workflow-markdown regression files into the canonical test
that owns each workflow aspect (execute-phase-*, plan-phase-*, quick-*, discuss-*,
worktree-cleanup, secure-phase, verify, update, settings, etc.), across 32 existing
suites. Verbatim block-scoped describe wrappers; 281 subtests conserved 1:1. No new
test files. Host-env pre-check: only gsd-settings-advanced spawns CLI and it sets no
GSD_WORKSTREAM/GSD_PROJECT value — no leak risk.

Regenerates regression-name allowlist (222->181), ratchets file-count allowlist
(verify 11->10), makes 30 relocated allow-test-rule exemptions issue-ref-compliant
(ADR-456; prunes 30 stale ids). lint:ci green.

Part of epic #1969. Closes #1973.

+ * Regression test for #2502: insert-phase does not update STATE.md's
+ * next-phase recommendation after inserting a decimal phase.
+ *
+ * Root cause: insert-phase.md's update_project_state step only added a
+ * "Roadmap Evolution" note to STATE.md, but never updated the "Current Phase"
+ * / next-run recommendation to point at the newly inserted phase.
+ *
+ * Fix: insert-phase.md must include a step that updates STATE.md's next-phase
+ * pointer (current_phase / next recommended run) to the newly inserted phase.
