Guard user.useConfigOnly behind identity check, offer to unset
conflicting pull.rebase, use dedicated signing key names to avoid
colliding with auth keys, back up SSH config before changes, place
new SSH directives in Host * blocks, and prompt for email in
allowed_signers setup.

SSH config hardening now presents directives in logical groups
(matching the git config UX) with reasoning for each:
- Host Verification: TOFU rationale, known_hosts exfiltration risk
- Key & Agent Management: key enumeration attack, passphrase fatigue
- Algorithm Restrictions: downgrade attack, intentional RSA breakage
Each group batches its directives into a single prompt instead of
asking one-by-one.
Bump version to 0.3.1.

FIDO2 hardware key generation now handles diverse security keys:
- Detect ed25519-sk vs ecdsa-sk support via ykman/fido2-token, with
automatic fallback chain: ed25519-sk → ecdsa-sk → ecdsa-sk -O resident
- Detect FIDO hardware by HID usage page (0xF1D0) instead of hardcoded
Yubico vendor ID — works with SoloKeys, Titan, Nitrokey, etc.
- Check libfido2 availability via ldconfig, dpkg-query, and rpm
- Warn on Qubes OS vhci_hcd USB passthrough (corrupts CTAP2 messages)
- Suppress admin recommendations when dependency is missing so install
instructions stay visible
- Accept ecdsa-sk keys in signing key filter
New --reset-signing flag clears git signing config, removes
allowed_signers entries, and moves/deletes key files so a fresh key
can be generated.
Bump version to 0.3.0.
