File Scanner

Probe: file_scanner.metadata.auto_dispatch — recursive scanner that detects and dispatches.

The meta-probe: crawls a directory, classifies files, detects partition patterns, and dispatches to the appropriate sub-probe (Excel, Power BI, Tableau, CSV, JSON).

Also detects: - yyyy-mm, yyyy/mm/dd, date=YYYYMMDD partition patterns - Hive-style partitions (key=value directories) - Glob patterns in directory structures
