Update fip-0016.md (#1174)

* Update fip-0016.md

This PR updates FIP-0016 status to Rejected.

Reason: After community and core team discussions, it was agreed that while FIP-0016 offered flexibility for miners, it conflicted with Filecoin’s long-term goals around economic alignment, on-chain transparency, and scalability. Similar functionality can already be achieved via sector-sized self-deals, and successor proposals like FIP-0017 address related upgrade use cases in a protocol-aligned way.

Closing this proposal as no further action is planned.

* Update FIPS/fip-0016.md
