Fix Windows compatibility: encoding, installer hints, interpreter name

- watch.py: drop the ⚠️ emoji from the long-video warning; cp1252
  consoles on Windows couldn't encode it and the script crashed.
- setup.py: add a Windows branch that prints winget / pip install
  commands, matching what the README already promised.
- SKILL.md: note that Windows users must invoke the scripts with
  `python`, not `python3` (which is the Microsoft Store stub).

+## [0.1.2] — 2026-04-24

+### Fixed
+- Windows console crash: removed the emoji from the long-video warning in `watch.py`; cp1252 consoles couldn't encode it.
+- `setup.py` now prints `winget` / `pip` install commands on Windows instead of "unsupported platform" — matches what the README already promised.
+
+### Changed
+- `SKILL.md` notes that on Windows the scripts must be invoked with `python`, not `python3` (the latter is the Microsoft Store stub on Windows).
