Remove exec/shell_exec from update checker and domain lookups

Update checker (fetchUpdates) no longer shells out to git:

- Current commit read directly from .git/HEAD, following the branch
  ref through loose refs with a packed-refs fallback (survives git gc);
  detached HEAD handled
- Latest commit fetched from the GitHub API via curl using the
  Accept: application/vnd.github.sha header (returns bare SHA, no
  JSON parsing)
- Repo owner/name derived from the origin remote in .git/config so
  forks check against their own remote, falling back to
  itflow-org/itflow
- Failures now distinguish unreadable .git (permissions) from API
  errors (network/rate limit) instead of silently returning empty

Domain lookups no longer shell out to dig and whois:

- DNS records (A/NS/MX/TXT) via dns_get_record()
- Registration data via RDAP (JSON over HTTPS, curl), the ICANN
  successor to port-43 whois; RDAP server per TLD resolved from
  IANA's bootstrap registry, cached locally for a week, rdap.org as
  secondary lookup
- Expiration date from RDAP's structured expiration event, replacing
  regex/date-format guessing for RDAP-covered TLDs
- Port-43 whois retained as socket-based fallback (fsockopen) for
  ccTLDs without RDAP, with IANA server discovery and one registrar
  referral follow
- RDAP responses cached per-run: getDomainRecords() and
  getDomainExpirationDate() on the same domain = one HTTP request

Fixes whois rate limiting, removes the exec dependency for hardened
hosts (Snuffleupagus etc.), and eliminates the shell injection
surface - no shell, nothing to escape.
