feat: add ATS & keyword verification pass to /apply's compile-and-inspect loop (#40)

Browse Source 
An ATS reads the compiled PDF's embedded text layer, not the rendered page,
and LaTeX can silently produce PDFs whose text extracts as garbage: icon
glyphs where contact details should be, (cid:*) markers from fonts without
Unicode mappings, interleaved lines from multi-column layouts. This matters
more now that /add-template lets users bring arbitrary templates. The
existing Step 5 loop verifies what a human sees; this adds verification of
what a parser sees.

New Step 5d in /apply (CV only - cover letters rarely go through keyword
screening; cleanup renumbered to 5e):

- Extract the CV PDF's text layer with pdftotext -layout. pdftotext
  (poppler) is an optional dependency: if missing, the mechanical check is
  skipped with a warning and keyword coverage falls back to the visual PDF
  read - the same graceful-skip pattern as salary_lookup.py
- Parseability checks verified against a real extraction of the stock
  template: email/phone must survive as literal text (fontawesome icons
  extract as harmless glyph-name noise like MOBILE-ALT/Envelope, but a
  contact detail carried only by an icon or hyperlink is invisible to ATS),
  no (cid:*) or replacement-character garbage, reading order matching
  visual order, dates present
- Keyword coverage reuses the required/preferred list from Step 1, matched
  in the posting's language, reported as covered / synonym-only /
  missing-have-it / missing-gap. Honesty rule enforced: keywords the
  profile genuinely supports get added to experience bullets; genuine gaps
  stay visible, never stuffed

Integration: CLAUDE.md verification checklist section, ATS Parseability
guidance in 05-cv-templates.md, narrow Bash(pdftotext:*) entry in the
pre-approved permissions (keeping with the tightened scope from #27),
cv/*.txt gitignored (extraction is personal data; also deleted by the
step itself), and optional-dependency docs in README and SETUP.

@@ -52,6 +52,16 @@ Install a LaTeX distribution to compile the generated `.tex` files to PDF:
The CV compiles with `lualatex` (pdflatex often fails on modern MiKTeX installs with `fontawesome5` font-expansion errors). The cover letter compiles with `xelatex` because `cover.cls` requires `fontspec` for its custom Lato/Raleway fonts.
### Optional: pdftotext (for the ATS check)
`/apply` runs an ATS parseability check on the compiled CV: it extracts the PDF's text layer and verifies contact details, reading order, and keyword coverage the way an applicant-tracking system sees them. This uses `pdftotext` from [poppler](https://poppler.freedesktop.org/), which is not part of TeX distributions:
- **macOS:** `brew install poppler`
- **Debian/Ubuntu:** `sudo apt install poppler-utils`
- **Windows:** `choco install poppler`
If `pdftotext` is missing, `/apply` skips the mechanical check with a warning and falls back to a visual keyword review — everything else works normally.
