Add ingest command for local file and dump import

New 'mosaic ingest' CLI command bypasses HTTP collection to import
raw documents (PDF, HTML, text) or pre-extracted JSONL data directly
into the pipeline.

Modes:
- Single/multiple files: -f file1.pdf -f file2.html -s source_name
- Directory bulk import: -d /path/to/dump/ -s source_name -r
- JSONL extracted data: -f data.jsonl -s name -c tools
- Real-time watch: -d /incoming/ -s name -w (polls every 2s)
- Auto-parse: --parse flag runs parser on newly ingested docs

Files are hashed, deduplicated, and stored in the cache using the
same hash-sharded scheme as HTTP-collected documents.
