What to build

Decouple high-level delta cache merging and Gmail cross-folder label enrichment from MailboxGateway, moving them into MailboxPipeline. Keep MailboxGateway focused purely on IMAP protocol communication, folder selection, and message fetching/moving.

Acceptance criteria

Refactor MailboxGateway::scan to perform batch IMAP header fetching without internal delta cache merging.
Move delta UID merging and Gmail with_merged_labels deduplication logic into MailboxPipeline::scan.
Simplify FakeImapTransport and protocol tests to focus on transport verification.
Ensure end-to-end incremental scan tests in est_gateway_and_cache.rs and est_pipeline_and_audit.rs pass.
Ensure cargo fmt and cargo clippy --all-targets --all-features -- -D warnings pass cleanly.

Decoupled delta caching and Gmail label enrichment from MailboxGateway to MailboxPipeline. MailboxGateway now performs raw batch header fetching without cache or deduplication dependencies. All 71 tests pass.
