v1.3.2 — PDF-by-default for Resume/Cover, fix silent Markdown fallback

[1.3.2] - 2026-07-12

Fixed

• Resume/Cover Letter silently uploaded to Drive as Markdown instead of
  PDF. The [pdf] extra (fpdf2) was a separate, easy-to-forget install
  step from [drive] — a missing fpdf2 degraded every Resume/Cover
  upload to .md with only a per-file warning, easy to miss. fpdf2 is
  now bundled into the [drive] extra, so pip install -e ".[drive]"
  alone gets PDF rendering by default; careeros doctor (with
  drive.enabled: true) now also proactively checks for it and FAILs with
  a clear fix if it's ever missing, instead of only surfacing a buried
  warning during daily.

• Only Resume and Cover Letter ever attempt PDF now. Application
  Answers, Evaluation, and Deep Report always upload as Markdown — not
  "PDF with a fallback," simply never attempted, since only Resume/Cover
  are ever attached to a job application.

• A Resume/Cover previously uploaded as .md (before PDF rendering was
  available) is no longer left orphaned in Drive once PDF rendering
  works. Drive matches existing files by exact filename, so a new
  .pdf upload didn't replace an old .md — both used to sit side by
  side in the flat Drive folder. Re-uploading now explicitly deletes the
  stale .md when a .pdf supersedes it for the same job.

• Edge case, found during this release's own verification: the stale-.md cleanup above now also handles two different jobs that happen to share the exact same Company/Role string (a genuine name collision, disambiguated with a numeric suffix like ... (2).md) — the cleanup previously only checked the un-suffixed base filename.
