What is new in TrackNotch 1.1.2

## What's new

**Fix: runaway CPU and battery drain**

On machines with heavy Claude Code usage, TrackNotch could pin the CPU (~285% measured) and drain the battery. While Claude was active, every 3 second poll re-parsed every session file from the past 7 days, and nothing stopped those scans from overlapping.

- Scans no longer overlap: a new one is skipped while the previous is still running
- Incremental scanning: each file is read from where the last scan stopped, so only new lines are parsed
- Lines that are not assistant messages are skipped before JSON parsing
- Context window value comes from cached state instead of re-reading the session file

Result: steady state CPU drops from ~285% to under 1% with Claude active. Usage numbers are calculated exactly as before.

Also includes a build fix so TrackNotch compiles on Xcode 27.
