fix: remove timestamp from generated contracts.ts to prevent churn (smart-mcp-proxy#246)

The generate-types command embedded a timestamp in the generated
TypeScript file, causing it to change on every build even when the
actual type definitions hadn't changed. This led to:
- Accidental commits of timestamp-only changes
- Unnecessary merge conflicts between branches
- Noisy git status after every build

Remove the timestamp line entirely. The 'DO NOT EDIT' comment already
communicates the file is auto-generated, and git history shows when
the file actually changed.

Fixes smart-mcp-proxy#245
