- Extracted fetch mocking logic into reusable `hookFetch()` utility function with middleware-style handler pattern.

- Exported `hookFetch` from utils public API to enable consistent fetch mocking across packages.
- Added Bun version validation at startup to enforce minimum version 1.3.7 for JSONL session parsing.
