test(#1976): consolidate 17 agent regression tests into agent-contract suites

Fold 17 issue-named agent-markdown regression files into their canonical agent
suites: agent-frontmatter (shared agent-body-contract catch-all: read-loop guards,
retired-slash-ref bans, sycophancy hardening, doc-writer/code-fixer/review-fix/mapper
contracts, write-truncation), planner-language-regression (planner directive/grep/phase
contract), executor-mvp-tdd-section, verifier-behavior-unverified, intel, and
research-agent-profiles. Verbatim block-scoped describe wrappers; 98 subtests conserved
1:1. All unit (markdown-content) tests — no CLI/env surface. No new files.

Regenerates regression-name allowlist (222->207), ratchets file-count allowlist (intel
entry removed, phase 4->3), makes 13 relocated allow-test-rule exemptions issue-ref-
compliant (ADR-456; prunes stale ids). No CONTEXT.md/ADR refs named the moved files.
lint:ci green.

Part of epic #1969. Closes #1976.
