feat(nadia): Update CLAUDE.md with CI configuration reference

All acceptance criteria verified:

| Criterion | Status |
|---|---|
| CLAUDE.md gains a `## CI` section | Line 33-38 |
| Documents `.gitea/workflows/ci.yml` as CI file | Line 34 |
| Documents push triggers on `main` and `master` | Line 35 |
| Documents CI runs `make verify` | Line 36 |
| All existing content preserved | All original sections intact |
| File starts with `# retoor <retoor@molodetz.nl>` header | Line 1 |
| No placeholder or TODO content | Confirmed |

Outcome: done
Changed: CLAUDE.md:1,33-38
Verified by: `make verify` — passed (61 tests, 0 failures, 0 warnings)
Findings:
- CLAUDE.md now has a `## CI` section documenting `.gitea/workflows/ci.yml`, push triggers on `main`/`master`, and `make verify` as the CI command
Open: none
Confidence: high — all acceptance criteria met, verification passes
