Silence the macOS __eh_frame linker note; wire kigi-bin into workspace lints

macOS ld cannot encode >16MB of __eh_frame in its compact unwind table and
says so on every debug link of the large binary. All profiles build with
panic=abort, so Rust never unwinds and the note's exception-handling caveat
does not apply. Allow rust.linker_messages at the workspace level with that
rationale, and give kigi-bin the missing [lints] workspace = true (it was
not inheriting workspace lints at all). Also drop the stale xAI authors
field and Grok wording from the kigi-bin manifest.
