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.

Detect Homebrew openssh by checking for ssh-sk-helper binary instead
of running ssh-keygen (which blocks waiting for a FIDO touch).

Use Homebrew ssh-keygen for FIDO2 key generation on macOS instead of
searching for libsk-libfido2.dylib (removed in modern openssh). Group
interactive apply prompts into 6 categories with explanations. Fix
Linux gitleaks install hint to show apt/dnf instead of brew.

Replace ~25 individual y/n prompts with 6 logical groups, each showing
a table of pending changes with one-line explanations before prompting.
Also fix FIDO2 middleware detection (needs brew openssh, not just libfido2).

Remove unused SIGNING_KEY_PATH variable (dead code), add trap for
temp file cleanup in apply_ssh_directive, add -- separator before
ssh-keygen path arguments, add info message when falling back to
in-memory credential cache on Linux.

Warn users in the signing wizard that reusing the same signing key
across personal and work accounts enables cross-platform identity
correlation. Recommend separate keys per org with git includeIf.
Also added to admin recommendations section.
