fix(resume): escape < before "10 min" so Typst doesn't parse it as a label

The Portfolio Template entry's bullet "deploy to GitHub Pages in <10 min"
landed on personal in PR #26 with an unescaped <, which Typst (rendercv's
backend) interprets as the start of a <label> token — failing the build
with "unclosed label" and skipping the PDF regeneration.

Fix: escape with double backslash in YAML (\\<), matching the pattern
already used elsewhere in the resume (\\<0.22%, \\<5s, \\>95%, etc.).
After YAML parse → \< on the wire → Typst treats as literal <.

Verified locally: rendercv v2.3 (CI version) renders the PDF successfully
after the fix.
