Fix stale comments to match current code

Audited comments project-wide against the current implementation:

- scripts/install.sh, scripts/uninstall.sh: header curl URLs pointed at a
  root-level install.sh/uninstall.sh, but the files live under scripts/ —
  the documented command 404'd. Corrected to the scripts/ path (matching
  the README and the actual file location).
- src/move.ts: header said it ties "four logic modules" and omitted
  editor.ts; the --edit terminal action was also missing from the order of
  operations. Both corrected.
- src/config.ts: numeric Config fields are all milliseconds now; dropped the
  stale "pixels" unit left over from stepCount/stepSize.

Comments-only (plus two script header lines); tsc clean, 64 tests pass.
