Implement a strictly compliant I-RegExp parsing mode

🤖 Augment PR Summary

Summary: This PR adds a new “I-Regexp” regular-expression dialect intended to follow RFC 9485 more strictly than the existing permissive mode.

Changes:

• Introduces RegexDialect::IRegexp in the public API and documents whole-input matching semantics.
• Adds src/core/regex/iregexp.h, which validates patterns against the RFC 9485 grammar and translates them into a PCRE2 pattern (anchored with \A(?: … )\z and mapping . to [^\n\r]).
• Refactors the existing permissive preprocessor into permissive.h (translate_permissive, PermissiveResult) and updates the build to include the renamed headers.
• Updates to_regex() to compile either the RFC9485 translation or the permissive translation, and disables capture groups for the RFC9485 dialect.
• Adds an extensive new test suite (regex_rfc9485_matches_test.cc) covering matching behavior and invalid-pattern rejection for the new dialect.

Technical Notes: The I-Regexp path is implemented as a grammar-aware translator (not a new matching engine) and relies on PCRE2 options to enforce Unicode behavior and whole-string matching.
