feat(cv): Phase 2.1-b — extract Projects, Certifications, and languages-from-prose

The structured model and StructuredCvProfileJson.FromSections already map Projects/Certifications/Languages headings, but the AI normalize prompt never emitted them, so on the benchmark CV the entire Projects section and the in-summary languages (English Native, Norwegian B1) were silently dropped. This closes that gap upstream — no backend schema or data change. ai-service (tools/summarizer/app.py): - /cv/normalize: added # Projects and # Certifications headings; a languages-from-prose rule (pull "native English", "Norwegian at B1" out of the summary even with no Languages section; ignore programming languages); and skill-group prefix stripping ("Development:", "DevOps & Infrastructure:", "Practices:" dropped, only the skills kept). - /cv/classify-block: Projects and Certifications added to the section enum + rules (fallback path). Backend: - LooksLikeNormalizedMarkdownCv now recognises # Projects / # Certifications so those CVs still take the markdown assembly path. Tests: - CvExtractionCoverageTests (4) lock the C# mapping of Projects, Certifications and Languages sections into the structured profile. - ai-service test_classify_block_supports_projects_section (1). 426 backend tests, 17 ai-service tests pass; app.py compiles. The LLM behaviour (prompt -> headings) needs Ollama to observe and was not run here; the C# side that consumes the headings is proven and the prompt change is additive. Merge-not-replace + the review screen are the next increment (2.1-a, approved: always-review, conservative merge). Deployment: these prompts live in the ai-service container, which deploy.sh does not rebuild by default -- deploy with DEPLOY_BUILD_AI_SERVICE=true or the change won't take effect.

+// already map Projects, Certifications and Languages headings into the profile; the gap was upstream
+// (the AI /cv/normalize prompt never emitted those headings, so the sections were dropped). These
+// tests lock the C# side so that once the normalized markdown carries # Projects / # Certifications /
+// # Languages, they reach the structured profile — and so a future change can't silently regress it.
+//
+// Content shapes mirror what the (fixed) normalizer produces for the benchmark CV
+// (Connor Babbington): a Projects section, and languages stated as "Name: Level".
