feat: Address::p2a
What changed, and why it matters
This commit adds a small, public helper function to create a new type of Bitcoin address called 'pay-to-anchor' (P2A). It is a pure feature addition with no visible bug fix or security-related change. There is no indication of a vulnerability being patched.
No security action needed; review as a normal feature addition.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff adds Address::p2a(hrp) in bitcoin/src/address/mod.rs, which delegates to WitnessProgram::p2a() and Address::from_witness_program(). It is a 5-line feature addition exposing the existing P2A witness-program constructor as an address constructor. No existing logic is modified, no bounds checks are changed, and no security-sensitive code paths are touched.
