fix: add --yes flag to bypass confirmation in /skills install and uninstall (#1647)

Fixes hanging when using /skills install or /skills uninstall from the
TUI — bare input() calls hang inside prompt_toolkit's event loop.

Changes:
- Add skip_confirm parameter to do_install() and do_uninstall()
- Separate --yes/-y (confirmation bypass) from --force (scan override)
  in both argparse and slash command handlers
- Update usage hint for /skills uninstall to show [--yes]

The original PR (#1595) accidentally deleted the install_from_quarantine()
call, which would have broken all installs. That bug is not present here.

Based on PR #1595 by 333Alden333.
