Summary

• Require published tempoch 0.11.2 and tempoch-ffi 0.11.2 across the Rust and C FFI workspace.
• Prepare siderust and siderust-ffi v0.18.1; report FFI version 1801 and update CITATION.cff and the FFI dependency note.
• Refresh Cargo.lock with the published crates.io checksums and add a focused CHANGELOG.md patch entry.

Why

Tempoch 0.11.2 fixes the EOP end-coverage defect: fractional MJDs beyond the last stored IERS sample and non-finite epochs now fail lookup instead of returning a stale final sample. In-range interpolation, leap-second-aware UT1, public APIs and binary carrier layouts are unchanged.

Validation

Run existing workspace CI (format, clippy, tests, locked dependency resolution and supported features). No tag or publication is part of this PR.

Upstream: Siderust/tempoch#26.
