First submission for the 100M row challenge.

Approach:

• Stream input using fgets
• Extract path and date via strpos/substr
• Aggregate counts in nested arrays
• Sort dates per path for deterministic output
• Output JSON with JSON_PRETTY_PRINT

Validation not passes with php tempest data:validate unless converted to CRLF like test-data-expected.json (commented for now, let's see...)
