0587c56091 kernel: Expose context-free block validation (w0xlt)
71f827c3c2 kernel: Expose consensus parameters (`btck_ConsensusParams`) (w0xlt)

Pull request description:

  This PR exposes Bitcoin Core’s context‑free block checks to library users via a new C API entry point, `btck_check_block_context_free`.

  Callers can validate a block’s structure (size/weight, coinbase rules, per‑tx context‑free checks) and optionally re‑run Proof‑of‑Work and Merkle‑root verification without touching chainstate, the block index, or the UTXO set.

  Rationale
  Clients embedding the kernel need a pure block sanity check without requiring node state or disk writes (candidate block validation, for example). This API offers that surface in a single call, with optional PoW/Merkle toggles to avoid redundant work when the header has already been validated or when Merkle verification is deferred.
