Introduces fluss-gateway as an independent Cargo workspace with library and executable entry points: strict configuration with stable exit codes, the shared error envelope, request-id/body-size/deadline middleware, the FIP-49 GET /health endpoint, REST and metrics listeners, task supervision with SIGTERM draining, and the OpenAPI 3.1 document generated from the typed router.

…uster harness Covers the shared HTTP contract over a real listener, the compiled binary's startup, health, SIGTERM draining and exit codes, and a self-test of the fixed-version dockerized Fluss cluster harness that later capabilities reuse for their end-to-end suites. Co-authored-by: gstamatakis95 <126914070+gstamatakis95@users.noreply.github.com>
Runs the gateway workspace's build, unit tests, license headers, formatting, clippy and rustdoc, checks the checked-in OpenAPI document for drift and validates it externally, and runs the end-to-end suite in a job that fails rather than skipping silently when a selected scenario cannot start.

Purpose
Linked issue: close #3958
First PR of FIP-49: the Gateway runtime and HTTP foundation. Authentication, the Fluss backend and the data
APIs come in follow-up issues.
Distilled from the FIP-49 PoC; the foundation was written by @gstamatakis95 and is credited via
Co-authored-by.Brief change log

66 tests: unit tests, the HTTP contract over a real listener, and the compiled binary's startup, health, SIGTERM and exit codes. A
