agent/utils.py:
- Add job_institution(job) — eliminates repeated .get("institution", .get("company",...))
pattern; the "company" fallback was dead (no scraper ever sets it)
- Add job_description(job, max_chars) — eliminates repeated [:3000] truncation pattern
agent/job_searcher.py:
- Remove _TYPE_QUERY dict (defined but never referenced anywhere)
- Move _MLSCI_NON_COUNTRY from inside the loop body to module-level frozenset
- Fix module docstring (remove stale FindAPhD/jobs.ac.uk-only references)
agent/job_matcher.py, cover_letter.py, cv_tailor.py:
- Use job_institution() and job_description() from utils
app.py:
- Use job_institution() in all 7 display/logic locations
