v0.1 prep: editing, backdating, text import, release infra

Journal:
- Full edit & delete for experiences, doses, timeline events, and substances.
- Backdate everything via datetime pickers (log past experiences accurately).

Import from text:
- Paste a free-text account; a local model (Ollama, JSON mode) extracts a
  structured experience — substances, doses, timeline — for review before saving.
  New commands parse_experience / import_experience. Verified against a live model
  (correctly pulled multiple doses incl. a null amount for "a couple of beers").

Release infrastructure (toward a shippable binary):
- Own app icon (journal mark) replacing the placeholder Cairn icon; pruned
  unused mobile icon sets.
- GitHub Actions release workflow (tauri-action) — universal macOS .dmg + Linux
  AppImage/.deb/.rpm on v* tags; signs when APPLE_* secrets exist, else unsigned.
- Fix bundle identifier com.fieldnotes.app -> com.fieldnotes.journal (the .app
  suffix conflicts with the macOS bundle extension). Verified `tauri build`
  produces a working .app + .dmg.
- README: document import + companion.
