v0.1.0 -- first public release

Render Strava activity into stylized heatmap posters and inline SVG.
Real polyline-circle obfuscation. Privacy flags for shippable renders.

Highlights
- patinate auth/sync/fetch-osm/render flow, end-to-end for one
  rider in one city.
- Real polyline-circle clipping (replaces v0-era naive start-point
  check) with a load-bearing privacy invariant test.
- --anonymize + --obfuscation-radius-m for renders destined for
  public publication.
- Four embedded themes (noir_heat, blueprint_heat, warm_beige,
  cycle_heat) plus --themes-dir for custom JSON themes.
- --web preset (single-layer heat, precision-1 coords, no minor
  roads) for inline page embeds.
- --heat-bloom + --heat-alpha runtime knobs to tune the glow stack
  per render.
- 44 lib tests, cargo audit clean, cargo deny clean, clippy clean
  on rust 1.94.
