Regex Search and Replace

Regex Search and Replace is an independent multi-threaded developer search
and batch replacement tool for Linux source trees, inspired by classic
grepWin workflows.

Key Features:
- Multi-Threaded RegEx and Literal Search: scan source trees across folders
with wildcard file masks, excluded directory filters, size/date limits,
case sensitivity, dot-matches-newline, multiline, whole-word matching,
and automatic NUL-byte binary file skipping.
- Side-by-Side Dry-Run Diff Preview: inspect matched lines with detected
file encoding, line numbers, match counts, and highlighted Old vs New
replaced lines before modifying any file on disk.
- Safe Batch Replace and 1-Click Rollback: execute multi-file replacements
with automatic .bak backup creation and 1-click Undo/Restore rollback,
plus cleanup for verified backups.
- Saved Presets and Hit Statistics: save named regex/replace presets in
JSON, view hit breakdowns by file extension, and export CSV or TXT reports.
- Bilingual English and Vietnamese interface with instant runtime switching.
