feat(apply): add mandatory PDF compile-and-inspect step and relevance-weighted cutting

Adds a new Step 5 to the /apply workflow that compiles the CV (lualatex)
and cover letter (xelatex) and visually inspects the resulting PDFs before
presenting them to the user. This catches page-break failures that .tex
review cannot detect: orphaned cventry titles, cover letters spilling to
a second page, and bullet fonts not matching body text.

Also introduces relevance-weighted cutting as the rule for shrinking an
overflowing CV: score each candidate line by (a) relevance to the posting,
(b) uniqueness in the document, and (c) load-bearing role in the cover
letter, then cut the lowest-total-score line first, regardless of section.
This replaces the old static "cut oldest section first" heuristic, which
was wrong whenever a relevant older-role bullet competed with an
irrelevant recent-role bullet.

Bundled with the earlier pending token-efficiency improvements to the
/apply workflow (inline draft passing to the reviewer, scoped reviewer
file reads, single end-of-workflow verification pass).

Changes:
- .claude/commands/apply.md: new Step 5 (Compile & Inspect PDFs), renumber
  old Step 5 to Step 6, update token-efficiency rules at top to reference
  Step 6 for the verification checklist
- .claude/skills/job-application-assistant/05-cv-templates.md: switch
  recommended compile engine from pdflatex to lualatex (pdflatex fails on
  modern MiKTeX with fontawesome5 font-expansion errors), add
  "Compile-and-Inspect Loop" section with needspace/enlargethispage
  patterns, add "Relevance-weighted cutting" section
- .claude/skills/job-application-assistant/06-cover-letter-templates.md:
  add compile command, add "Compile-and-Inspect Loop", document the
  "\lettercontent{} + itemize" pitfall and the required font-matching
  Raleway-Medium wrapper fix
- CLAUDE.md: add "Compiled PDF verification (MANDATORY)" checklist items

+### Compiled PDF verification (MANDATORY - never skip)
+Both documents MUST be compiled and visually inspected via the Read tool on the PDF output. "Looks fine in the .tex" is not acceptable - LaTeX page-break decisions are unpredictable. Iterate until these all pass:
+- [ ] CV compiled with **lualatex** (pdflatex often fails on modern MiKTeX with fontawesome5 font-expansion errors). Cover letter compiled with **xelatex** (cover.cls requires fontspec).
+- [ ] **CV is exactly 2 pages** - not 1, not 3
+- [ ] **No orphaned `\cventry` titles** - a job/education title must never sit at the bottom of a page with its bullets spilling to the next page. Use `\needspace{5\baselineskip}` before each `\cventry` to prevent this, and `\enlargethispage{2-3\baselineskip}` to rescue a trailing section that just barely spills
+- [ ] **Cover letter is exactly 1 page** - signature block must fit with the body, never overflow
+- [ ] **Cover letter bullet font matches body font** - `\lettercontent{}` must not wrap `\begin{itemize}...\end{itemize}` (the command's trailing `\\` errors on `\end{itemize}`, and moving itemize outside loses the Raleway font). Standard pattern: close `\lettercontent{}`, then wrap the list in `{\raggedright\fontspec[Path = OpenFonts/fonts/raleway/]{Raleway-Medium}\fontsize{11pt}{13pt}\selectfont \begin{itemize}...\end{itemize}\par}`
