First productized release: agent-first regex CLI with a stable JSON contract, standalone binaries and a product homepage.

replace command with backreference substitution and replacement count
match JSON output now includes per-match capture groups: index, name, value, start, end; absent groups are null

Explicit exit codes: 0 ok · 1 invalid regex · 2 usage error · 3 valid pattern, zero matches/replacements
Bilingual human output (--lang en|zh, REGEXMATE_LANG)
Parser support for lookarounds, atomic groups, flag groups, backreferences, POSIX classes and unicode classes \p{…}
--version, --help, stdin input for match/replace, NO_COLOR support
Standalone binaries for Windows, Linux and macOS, with SHA-256 checksums
Product homepage at https://jrtx.site/regexmate/ with tool-generated railroad diagrams

Clean node type names in JSON output (literal, quantifier, group, lookaround, … instead of internal re-* names)
Compile errors cleaned to a single friendly line
Repackaged as an installable Racket package: raco pkg install https://github.com/turinglambdaai/regexmate.git

Character-class items with symbolic escapes no longer confuse the explain/visualizer formatters
Empty matches no longer stall the match scan
