chore(openspec): archive elevation-profile-hardening

All 11 tasks complete (shipped in #581/#582/#583). Archive via
`openspec archive` (CLI 1.6.0):
- Creates openspec/specs/elevation-computation/spec.md — new capability
  (4 requirements: spike removal, threshold-filtered ascent/descent,
  cleaned profile series, per-day totals from cleaned data). Purpose
  filled in (CLI leaves TBD).
- Moves the change to openspec/changes/archive/2026-07-13-elevation-profile-hardening/.

Spec passes `openspec validate --strict`.
