docs: update TODO — mark error handling, PWA SW, launch_profiles editor as done; annotate slide control + kill_processes status

- Error handling + fallback: confirmed done (launcher_file_cont.svelte)
- PWA service worker chrome-extension guard: confirmed done (service-worker.js)
- Launcher config UI / launch_profiles editor: confirmed done (launcher_cfg_launch_timing.svelte)
- Slide control scripts: annotated partial state — Svelte buttons wired, Electron scripts still hardcoded, deferred post June 10
- kill_processes: documented as not started on Svelte side; noted Device tab length concern

Also bundle two prior-session Launcher fixes:
- VLC post_delay_ms: 2000 → 1500ms
- launcher_cfg_launch_timing: add min-w-22 to built-in/current delay display
