feat(ats): extract PDF text with pypdf before Poppler (#369)

* feat(ats): extract PDF text with pypdf before Poppler

Lead the ATS text-layer check with pypdf (BSD, optional pip install). Fall back to pdftotext -layout -enc UTF-8. No cache directory, no installer, no AGPL pymupdf. Windows users without Poppler still get a mechanical parseability check; visual review remains the last resort.

* Update verify_pdf.py

* Update apply.md

* Update verify_pdf.py

* Update verify_pdf.py

An ATS parser reads the PDF's embedded **text layer**, not the rendered page — a CV that passed visual inspection can still extract as garbage (icon glyphs where the contact details should be, scrambled reading order in multi-column layouts). This step verifies what a parser actually sees. It applies to the **CV only**; cover letters rarely go through keyword screening.
**Availability check:** run `pdftotext -v`. `pdftotext` (poppler) is an optional dependency, not part of TeX distributions. If it is missing, print a one-line warning that the mechanical parse check is skipped, do the keyword-coverage check (item 3 below) against your visual Read of the PDF instead, and note the degraded mode in the Step 6 report. Same graceful-skip pattern as the salary lookup. Keep the `-enc UTF-8` flag: Xpdf-based builds default to Latin-1 output, and without it a correct non-ASCII CV fails the replacement-character check below.
**Availability check:** extract with `python tools/verify_pdf.py` (tries **pypdf** first — BSD, `pip install pypdf` — then Poppler `pdftotext`).

Read the `.txt` file.
The command prints `extractor: pypdf` or `extractor: pdftotext`. Record that name in the Step 6 report. Read the `.txt` file. If that tool is unavailable, the Poppler fallback is:
```bash
cd cv && pdftotext -layout -enc UTF-8 main_<company>_<role>.pdf main_<company>_<role>.txt

Most employers run CVs through an ATS before a human sees them, and the ATS reads the PDF's embedded **text layer**, not the rendered page. A CV can pass visual inspection and still extract as garbage. After the layout passes the compile-and-inspect loop, verify the text layer:
```bash
cd cv && pdftotext -layout -enc UTF-8 main_<company>_<role>.pdf main_<company>_<role>.txt
python tools/verify_pdf.py cv/main_<company>_<role>.pdf --dump-text cv/main_<company>_<role>.txt
```
`pdftotext` comes from [poppler](https://poppler.freedesktop.org/), not the TeX distribution - it is an **optional** dependency. The `-enc UTF-8` flag is not optional: Xpdf-based `pdftotext` builds default to Latin-1 output, which makes every non-ASCII character in a perfectly good CV read back as a replacement character and fail the parseability check below for no real reason. If it is not installed, skip the mechanical check with a warning and rely on the visual PDF read for keyword coverage.
Extraction tries **pypdf** first (`pip install pypdf`, BSD license), then Poppler `pdftotext`. If a fallback still uses `pdftotext -layout`, it must also pass `-enc UTF-8`: Xpdf-based builds default to Latin-1, which makes every non-ASCII character in a perfectly good CV read back as a replacement character. If neither extractor is available, skip the mechanical check with a warning and rely on the visual PDF read for keyword coverage.
