copilot-swe-agent[bot] d7a8f48c1c Commit 3: Add test.cpp corpus wrapped in std::regex stubs; generate .expected 
Introduces cpp/ql/test/library-tests/regex/test.cpp with the Ruby regex
corpus mechanically translated to C++ string literals and wrapped in
std::regex construction calls using fully self-contained in-file stubs
(no #include of any external/standard header).

Stub surface:
  std::basic_regex<CharT>  constructor(const char*), constructor(const char*, int),
                           assign(const char*)
  std::regex               typedef for basic_regex<char>
  std::regex_match / regex_search / regex_replace  free functions

1:1 corpus mapping from regexp.rb:
  - All Ruby /regex/ literals translated to C++ "string" literals
    (each backslash doubled: /\d/ -> "\\d")
  - Dropped: /#{A}bc/ (Ruby string interpolation, no string-literal form)
  - Kept: a{,8}, .*m, \A, \z, \G, \h\H, (?'foo'...) — these are removed
    in commits 4 and 5 (keeping them here preserves 1:1 mapping)

Also removes `abstract` from RegExp class in ParseRegExp.qll so that all
StringLiterals are regex candidates (trivial syntactic gate; no dataflow).

.expected generated by:
  codeql test run --learn --search-path=. cpp/ql/test/library-tests/regex/
  (CodeQL CLI 2.26.1, bundled C/C++ extractor)
All 2 tests passed.
