v4.3.0

Restructured compileGlob() into three distinct phases:
1. Resolve glob patterns and clean ALL output directories upfront
2. Compile all TypeScript tasks (no filesystem cleanup during this phase)
3. Unpack all outputs after all compilations complete

This prevents XFS metadata corruption from rm operations overlapping
with TypeScript compilation writes to sibling directories.

 # Changelog
 
+## 2026-03-06 - 4.3.0 - feat(mod_logger)
+add centralized TsBuildLogger and replace ad-hoc console output with structured, colored logging
+
+- Add ts/mod_logger/classes.logger.ts providing header/step/detail/success/error/warn/indent utilities with ANSI color support
+- Export logger from ts/mod_logger/index.ts and re-export from ts/index.ts
+- Replace console.log/console.error/console.warn calls in mod_cli, mod_compiler, and mod_unpack with TsBuildLogger methods for consistent, hierarchical output
+- Refactor error-summary, emit and type-check output to use logger separators, colors, and structured messages
+
+## 2026-03-05 - 4.2.6 - fix(meta)
+no changes
+
+- Current package version: 4.2.5
+- No code or file changes detected in this commit; no release required
+
 ## 2026-03-05 - 4.2.5 - fix(compiler)
 yield to the event loop after TypeScript emit to allow pending microtasks and I/O to settle before reading or modifying the output directory
