v0.1.1 – UX Upgrade: Soft Keys & Saved Preferences

Highlights

• Added soft key bar (zoom, units, track length, demo, settings) with auto scaling
• Introduced settings screen overlay with staged edits (Save / Back behavior)
• Persistent JSON settings: units, default range, track length preset, demo mode, altitude filter band, north‑up lock
• Centralized versioning via version and badges in README

UI / UX

• North‑up lock toggle + rotation when unlocked
• Altitude filter bands (All, 0–5k, 5–10k, 10–20k, >20k) applied to rendering and labels
• Demo mode: looping sample trace, temporary recenter, DEMO badge
• Trail length presets with automatic trimming and pinned track retention

Infrastructure

• Debounced atomic settings writes (~/.pocketscope/settings.json) with env override
• Config watcher publishes change events for hot reload
• CLI now reports version from single source

Testing

• Added/updated UI tests: soft keys, settings persistence, altitude filter, north‑up lock, track trimming

Internal

• Centralized version (pyproject attr -> pocketscope.version)
• README badges for tag/release

Upgrade Notes

• After pulling: no manual migration needed; settings file will be created on first run
• Tag: v0.1.1 (matches version)
