store: remove dead code and move params to config
Remove:
- score_weight() - never called
- position field on Node - never read (was for export)
- Provenance enum - inline helper for capnp migration
- migrate_transcript_progress + CLI command
- init_from_markdown, import_file, ingest_units
- export command and export_to_markdown
- RetrievalEvent, GapRecord types
- classify_filename, new_transcript_segment
Move spreading activation params to Config:
- default_node_weight, edge_decay, max_hops, min_activation
- Remove Params struct and StoreView::params()
Simplify cmd_init to just seed identity via upsert().
Simplify cmd_import to use parse_units + upsert directly.
