5ec19ec367 feat: FIDO2 key type auto-detection, fallback chain, and --reset-signing
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.

dd6257985b fix: v0.2.3 e2e distro loop, FIDO2 freeze, grouped prompts
Fix e2e.sh distro iteration broken by IFS setting (use bash array).
Fix FIDO2 detection freezing on macOS (check ssh-sk-helper, don't
invoke ssh-keygen). Group apply prompts into 6 categories. Fix Linux
gitleaks install hint.

d8e7665e72 fix: FIDO2 detection no longer freezes on macOS
Detect Homebrew openssh by checking for ssh-sk-helper binary instead
of running ssh-keygen (which blocks waiting for a FIDO touch).

475faf23df fix: v0.2.1 FIDO2 macOS keygen, grouped prompts, Linux hints
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.

09f6369bec refactor: group apply prompts with explanations
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).

ssh-keygen path arguments, add info message when falling back to
in-memory credential cache on Linux.

0af4409467 feat: add OSINT advisory about signing key reuse
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.

902d1abac0 fix: force base-10 in version_gte to prevent octal interpretation
Use 10#$var arithmetic prefix to avoid bash interpreting leading
zeros as octal (e.g., 08 or 09 would cause "value too great for
base" errors). 2 new tests (64 total).
