chore(install): optimize logging, speed, cleanup

- Version logged after [PASS] (not before) across all scripts
- Pre-cache brew package lists with log_info progress
- Read brew version from git describe cache (skip Ruby startup)
- Batch mise use -g calls (single invocation for all tools)
- Replace mise verify step with mise ls --current
- Parallel vim plugin pulls
- Skip donut compile when binary is fresh
- Pre-check macOS defaults before writing (skip fsync when unchanged)
- Pre-check dock state before dockutil calls
- Remove redundant 'already installed' skip logs
- Remove meetingbar and wispr-flow install scripts
- Renumber scripts to fill gaps
