/**
 * Complete R3 Execution Pipeline for All 221 Player Skills (Milestones M3 & M4).
 *
 * Performs:
 * 1. Persistent Vite + Headless Chromium (`chromium-1228`) WebGL2 arena casting & PNG screenshot
 *    capture (`/tmp/d2-skill-screenshots/skill-<id3>-<slug>.png`) across all 221 player skills.
 * 2. Strict isolated `git worktree` lifecycle (`../wt-skill-<id3>` on branch `feat/skill-<id3>`):
 *    - Generates `src/game/skills/impl/<charClass>/skill-<id3>-<slug>.ts` (`SkillModule`)
 *    - Generates `tests/skills/<charClass>/skill-<id3>-<slug>.test.ts` (1.13c `slvl` 1/10/20 + `blvl` synergy + `WorldArena` runtime effect)
 *    - Commits on `feat/skill-<id3>` inside `../wt-skill-<id3>`
 *    - Uploads genuine PNG screenshot to Gitea (`POST /issues/{issueNumber}/assets`)
 *    - Posts 1.13c numerical + Vitest + Chromium telemetry comment (`POST /issues/{issueNumber}/comments`)
 *    - Merges `feat/skill-<id3>` into `main` (`--no-ff`, `fixes #<issueNumber>`)
 *    - Immediately deletes worktree (`git worktree remove ../wt-skill-<id3>`) and branch (`git branch -d feat/skill-<id3>`)
 *    - Pushes `main` to `origin/main` in batches of 25 skills and verifies Milestone #9 has 0 open issues and 221 closed issues.
