v0.2.3

Fix: TLS probe on IP targets / 修复 IP 目标的 TLS 探测

• Bug: check_tls (and the tls probe behind it) sent the target address as TLS SNI unconditionally. Modern Node (≥ 20) rejects SNI for IP literals — ERR_TLS_SNI: Setting the TLS ServerName to an IP address is not permitted — so probing any IP target threw instead of reporting the certificate.
• Fix: SNI is now only sent for hostnames; IP targets let Node omit it automatically (RFC 6066 — SNI is not defined for IP addresses).
• Regression test: covers both an IP handshake (127.0.0.1) and a hostname handshake (localhost) against the local self-signed fixture server.
• Tooling: added the coverage ratchet gate (baseline 68.02%, run_tests.sh + .githooks/pre-commit); every code change must bump the version and may not lower coverage.

Test suite: 69 tests green (was 68).

v0.2.0 — WHOIS registry lookup + SOA/CAA DNS records

v0.2.0 (2026-08-26)

New tool: whois — WHOIS registry lookup over the classic TCP port 43 protocol:

• Automatic registry discovery via the whois.iana.org referral chain
• Best-effort TLD→registry fallback map (com/net/org/io/ai/co/me/xyz/app/dev/cn/uk/us/ca/…) for when IANA discovery is unreachable or returns no referral
• ARIN as the default registry for IP literals
• Raw WHOIS text (capped) plus a structured summary: registrar, statuses, created/updated/expiry dates, nameservers
• Graceful error results (never throws on network failure)

Extended dns_lookup — now supports SOA and CAA record types (10 total).

Other

• New config option whoisTimeoutMs (default 5000)
• 68 offline tests (was 50); TLS daysRemaining assertion is now clock-independent
• Still zero runtime dependencies — Node.js built-ins only
