Implemented and extended games2tools coverage beyond launchable games.

**Done**
- Added `toolHints` for all planned/non-launchable games (`18/18`), so coverage is now full:
  - `29/29` games have tool mappings.
- Generated a detailed manual QA checklist with concrete URLs, steps, and expected results:
  - [games2tools_manual_qa_checklist.txt](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\docs\dev\reports\games2tools_manual_qa_checklist.txt)

**Current Coverage**
- Launchable games with hints: `11/11`
- Planned games with hints: `18/18`
- Overall games with hints: `29/29`

**Files changed**
- [games.index.metadata.json](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\games\metadata\games.index.metadata.json)
- [games2tools_manual_qa_checklist.txt](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\docs\dev\reports\games2tools_manual_qa_checklist.txt)

**QA Pass Detail Highlights**
1. Preflight checks for local server, hard refresh, and console noise.
2. Global pass criteria for Tool filter behavior, roundtrip params, return path, and header return-line behavior.
3. Per-game matrix for all launchable games.
4. Per-game matrix for all planned/non-launchable games.
5. Failure logging template (`Game ID`, `Tool ID`, step, observed vs expected, screenshot).

Commit comment: `Expand Games2Tools mapping to all planned games and add detailed manual QA checklist with per-game roundtrip validation steps.`
