content: align landing geo to CV — Nantes relocation (tour CLN-9)

CLAUDE.md requires the profile/job-search state to stay consistent across
index.html and the CV. The CV stated a concrete Nantes relocation + a
hybride-Nantes option the landing lacked. Per owner decision, the CV is
canonical: propagate those facts into the landing (about paragraph +
callout) and update CLAUDE.md's geography note to match. No invented claims
— mirrors what the CV already states. CV unchanged (no PDF regen).
