SBA Scout Rust: two separate databases for Rust vs Python apps

Decision

The Rust rewrite maintains its own independent SQLite database, separate from the Python app.

App	DB Path	Size (approx)
Python	data/sba_scout.db	1.7 MB (full)
Rust	rust/data/sba_scout.db	491 KB (initial, grows after import)

Both paths are relative to the repo root. The Rust app's config.rs defaults db_path to data/sba_scout.db relative to cwd, which resolves to rust/data/sba_scout.db when running from the rust/ directory.

CSV Import Paths (Rust)

Default paths (relative to rust/ cwd):

• docs/sheets_export/BatterCalcs.csv
• docs/sheets_export/PitcherCalcs.csv

Rationale

The Rust rewrite is being developed on a separate branch (feat/rust-rewrite) and needs its own DB so development and testing don't interfere with the production Python app data.
