docs: add field test reports for Tiling Shell and Media Controls

[ZviBaratz]

Summary

• Tiling Shell field test report (session fix(ego-lint): reduce Just Perfection false positives #29): Compiled TypeScript extension, 64 files / 11K lines — identified constructor-from-enable FPs, arrow fn definition FPs, ternary guard FPs, single-line minification FP
• Media Controls field test report (session fix(ego-lint): add src/ layout license fallback and UUID-dir skip #30): MPRIS D-Bus controller, src/ layout, 17 files / 5K lines — identified onDestroy() cleanup recognition gap, provenance threshold too conservative, src/ metadata.json fallback missing
• Calibration lessons chore(main): release 0.1.1 #14-18 added to docs/internal/README.md (compiled TypeScript patterns)
• Development Workflow section added to CLAUDE.md (issue→branch→PR convention)
• Repository Workflow section added to CLAUDE.md

Closes #19

Test plan

• Documentation-only changes — no code affected
• Field test reports follow existing template format

Code review

Found 1 issue:

1. Documentation states guard-window: 0 for R-VER49-08/11, but the actual implementation (merged in PR fix(ego-lint): reduce Tiling Shell false positives #22, commit 0259065) uses guard-window: 1 because guard-window: 0 is rejected by apply-patterns.py --validate. This appears in three places and would mislead anyone following the docs into hitting a validation failure.

	15. **Arrow function definitions at module scope are lazy**: `const fn = () => Main.layoutManager.monitors` doesn't execute at module load time. The function body is deferred until the first call.
	16. **Same-line ternary guards need `guard-window: 0`**: Version compat patterns like `api.exists ? old(args) : new()` have the guard and deprecated API on the same line. `guard-window: 0` (match on current line only) handles this.

	| init/shell-modification (arrow fn) | `const fn = () => Main.x` treated as module-scope access | Detect arrow function definitions and skip | 1 |
	| R-VER49-08 | Same-line ternary `get_maximized ?` not recognized as guard | Added `guard-pattern: "get_maximized\\s*\\?"` with `guard-window: 0` | 1 |
	| R-VER49-11 | Same as R-VER49-08 | Same guard-pattern | 1 |

	4. **Same-line ternary guards need `guard-window: 0`**: Version compat patterns like `api.exists ? old(args) : new()` have the guard and the deprecated API on the same line. `guard-window: 0` handles this.

All three should say guard-window: 1 to match the validated implementation. See the fix commit for context: 0259065
