Add empty per-component subdirectories under src/{Analyser,Log,Parser,Pattern}/Minecraft/
with .gitkeep markers, plus MinecraftDetective stub extending the base Detective with
a TODO body. Smoke test under test/tests/Games/Minecraft/ asserts the detective is
instantiable. Introduces src/Pattern/ as a new top-level component directory.
Bulk substitution across all PHP files in src/ and test/. Covers
namespace declarations, use statements, fully-qualified class
references, and @package PHPDoc tags. No logic changes.
