Subject: feat: bound climb detection by matched official climbs

Detected climbs no longer absorb an official climb's range: official climbs
matched to the route by coordinates claim their stored start/end range, and
climb detection now runs only in the free regions around them. On ride 263 a
single absorbed Cat 2 ascent is split so creating a first-half official climb
lets the second half be detected on its own.

- ride: add Range, freeRegions, and DetectClimbs(claimed); exclude claimed
  ranges so a climb never overlaps one
- official_climb: MatchClimb now bounds-matches purely by coordinates without
  needing a detected climb; extract geo.Nearest shared helper
- rideanalysis: Analyze builds claimed climbs from matched official climbs and
  detects only in free regions; render official vs unmatched climbs separately
