feat(hdkeys): replace hardcoded DOMAIN_* integers with sha256-derived values

Issue #3 Phase 1. Domain indices are now computed as: domain_index(name) = sha256(name.encode())[:4] & 0x7FFFFFFF

This is the same pattern used for MUSE_PURPOSE — reproducible by anyone, no central registry, no registration-war for third-party domains.

New exports: - domain_index(name: str) -> int — compute any domain's index from its name - DOMAIN_GENERIC = domain_index('muse/generic') — repos with no domain plugin

Canonical name strings use the 'muse/<slug>' convention for first-party domains. Any third-party domain can derive its own index without coordination.

Updated tests: remove hardcoded 0/1/2/3 assertions, add snapshot tests for the concrete hash values, and add 31-bit range checks.
