v1.0.7

Fixed: `headless-tracker help` now prints the canonical `npx` Claude Desktop config (was `bunx`, which needed Bun). The old-Node SQLite error leads with "upgrade to Node 22.5+" instead of suggesting bunx.

Changed: split the 631-line `metamask.ts` into focused modules (`metamask-chains.ts`, `metamask-etherscan.ts`, and the connector class) with no behavior change. 332 tests green.
