refactor(agents): consolidate emphasis-marker density in top 4 agents (#2368) (#2412)

CHANGELOG.md

@@ -37,6 +37,7 @@ Format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 ### Changed
 - **`gsd-debugger` philosophy extracted to shared reference** — The 76-line `<philosophy>` block containing evergreen debugging disciplines (user-as-reporter framing, meta-debugging, foundation principles, cognitive-bias table, systematic investigation, when-to-restart protocol) is now in `get-shit-done/references/debugger-philosophy.md` and pulled into the agent via a single `@file` include. Same content, lighter per-dispatch context footprint (#2363)
 - **`gsd-planner`, `gsd-executor`, `gsd-debugger`, `gsd-verifier`, `gsd-phase-researcher`** — Migrated to `@file` includes for the mandatory-initial-read and project-skills-discovery boilerplate. Reduces per-dispatch context load without changing behavior (#2361)
+- **Consolidated emphasis-marker density in top 4 agent files** — `gsd-planner.md` (23 → 15), `gsd-phase-researcher.md` (14 → 9), `gsd-doc-writer.md` (11 → 6), and `gsd-executor.md` (10 → 7). Removed `CRITICAL:` prefixes from H2/H3 headings and dropped redundant `CRITICAL:` + `MUST` / `ALWAYS:` + `NEVER:` stacking. RFC-2119 `MUST`/`NEVER` verbs inside normative sentences are preserved. Behavior-preserving; no content removed (#2368)
 
 ### Fixed
 - **Broken `@planner-source-audit.md` relative references in `gsd-planner.md`** — Two locations referenced `@planner-source-audit.md` (resolves relative to working directory, almost always missing) instead of the correct absolute `@~/.claude/get-shit-done/references/planner-source-audit.md`. The planner's source audit discipline was silently unenforced (#2361)
