v0.1.0

feat(install): default to official extension IDs from web stores

Each browser now has a built-in default extension ID matching the
official Web Store / Add-ons listing, so `ptd install --browser chrome`
works without specifying `--extension-id`. Extra IDs (e.g. for unpacked
dev builds) can still be added and are merged alongside the defaults.

- Firefox: unchanged (already uses ptdepiler.ptplugins@gmail.com)
