pullfrog[bot] b6e6a8976c Replace Date.now() with performance.now() for duration measurements (#258)
* Replace Date.now() with performance.now() for duration measurements

- Import performance from node:perf_hooks in all affected files
- Update Timer and ThinkingTimer classes to use performance.now()
- Update activity tracking (markActivity, getIdleMs) to use performance.now()
- Update cache duration measurements to use performance.now()
- Update agent execution timing (cursor, opencode) to use performance.now()
- Update subprocess execution timing to use performance.now()
- Update API performance monitoring to use performance.now()
- Update prep phase timing to use performance.now()
- Update timer.test.ts to mock performance.now() instead of Date.now()

Benefits:
- Monotonic clock immune to system clock adjustments
- Higher precision (microsecond vs millisecond resolution)
- Purpose-built for performance measurement

Fixes #245

* fix lint.

* Round float durations to integers in logging

Preserve original behavior by rounding performance.now() float values
to integers when displaying/logging millisecond durations.

* fix lint.
