v1.4.0

Minor version adding glob.match, glob.quote_meta, and regex.globs_match
built-in implementations.

New Features

• Added glob.match built-in with full gobwas/glob-compatible pattern matching,
  including *, **, ?, character classes ([abc], [a-z], [!x]),
  brace alternatives ({foo,bar}), and configurable path delimiters.
• Added glob.quote_meta built-in for escaping glob metacharacters.
• Added regex.globs_match built-in for testing whether the intersection of
  two glob patterns matches a non-empty set of non-empty strings.

Bug Fixes

• Fixed regex.find_all_string_submatch to advance by one Unicode codepoint
  after a zero-length match, preventing infinite loops and matching Go's
  regexp.FindAllStringSubmatch behavior.

Build System / Packaging

• Fixed vcpkg portfile.cmake REF to use v${VERSION} prefix, matching the
  actual git tag format.
• Added "supports": "!x86" constraint to vcpkg manifest.
• Bumped vcpkg OpenSSL minimum version from 3.0.0 to 3.0.2.

Test Infrastructure

• Extracted built-in-specific test cases from regocpp.yaml into a new
  builtins.yaml file with a dedicated CTest target (rego_test_builtins).
• Added 27 new test cases covering glob.match, glob.quote_meta, and
  regex.globs_match (including edge cases and error conditions).
