feat(profiles): add --no-skills toggle to create-profile sheet

Adds an "Empty profile (no skills)" toggle to the Mac create-profile
sheet, gated on `hasProfileNoSkills` (v0.13+). When ON, the create
flow appends `--no-skills` to `hermes profile create`. The toggle is
disabled (greyed out) when "Full copy of active profile" is on, per
WS-7 plan Decision H — a full clone copies skills wholesale, so
`--no-skills` would be a contradiction at the UX layer. The wire
itself stays permissive: a user can stack `--clone --no-skills` to
clone config but skip skills, which is a plausible workflow.

Defensive write-strip: even though the toggle is hidden on pre-v0.13
hosts, the call site reads `createNoSkills` through the capability
gate so a stale state value can't sneak `--no-skills` past argparse
on a CLI that doesn't know it.

iOS Profiles is read-only (per CLAUDE.md "v0.12 iOS catch-up
Phase H") so no toggle there.

TODO marker (WS-7-Q8) flags the assumed `--clone-all` interaction —
verify Hermes's behaviour with both flags during integration.
