Phase 2.7.1: Extension Rename

Renames the user-facing extension from "Xdebug" to "PHP Debugger" while maintaining full backward compatibility as a drop-in replacement.

Changes (8 files, +178/-37)

Extension identity:

• Module name: php_debugger (phpinfo, extension_loaded)
• extension_loaded("xdebug") still returns true (compat alias)
• Version: 0.1.0-dev

INI dual-prefix:

• xdebug.* settings unchanged (existing configs work as-is)
• php_debugger.* aliases added

Function aliases:

• php_debugger_break(), php_debugger_connect_to_client(), php_debugger_info(), php_debugger_is_debugger_active(), php_debugger_notify()
• All xdebug_*() originals still work

Trigger aliases:

• PHP_DEBUGGER_SESSION, PHP_DEBUGGER_SESSION_START/STOP, PHP_DEBUGGER_TRIGGER, PHP_DEBUGGER_CONFIG, PHP_DEBUGGER_IGNORE
• All XDEBUG_* originals still work (preferred if both set)

Build system:

• Output: php_debugger.so / php_debugger.dll
• Configure: --enable-php-debugger

phpinfo:

• Shows "PHP Debugger" with "Based on Xdebug by Derick Rethans"

Quality gate

• ✅ extension_loaded for both names
• ✅ Both INI prefixes work
• ✅ Both function prefixes work
• ✅ Build produces modules/php_debugger.so
• ⚠️ 3 test diffs are cosmetic (DBGp init packet engine name changed)

License

Xdebug license §3-4 requires derived products not use the "Xdebug" name. This rename satisfies that requirement while keeping full backward compatibility.
