Description

This PR adds a lightweight API to inspect SpendingConditions directly from a Token and without requiring Mint keysets:

New helpers on Token:
- spending_conditions
- p2pk_pubkeys
- p2pk_refund_pubkeys
- htlc_hashes
- locktimes
New token_secrets() unifies V3/V4 proof traversal and removes code duplication.
Bypasses short→long keyset-id mapping since only Secret is needed for condition parsing.
Improves DX: external users can extract P2PK and HTLC metadata without mint context.

as @davidcaseria said we should also add these to cdk-ffi.

I wonder about the hashset as the return type is that handled well my uniffi? Should we just make it a list and convert from hashset to list internally to make it a unique list. These are also going to be small lists so can probably avoid the hashset all together and just do a contains check.
