feat: Nostr-native data models + initial schema
models/db.rs: User keyed by pubkey_hash/nostr_pubkey/username (pubkey_hash and seed_fingerprint peppered at rest); Wallet, Session (platform=extension|web|nostr), UserKey, GrinSlatepack, AuditLog. Dropped all telegram/discord/social-identity columns and every tip/social/swap struct (swaps land as their own feature unit). migrations/20260622000001_initial_schema: consolidated clean schema; enum types; UNIQUE on identity columns; FK ON DELETE (CASCADE/SET NULL) for self-service erasure; indexes on every lookup column. PostgreSQL 13+.

-- Initial schema for smirk-backend-core.
|
||||
--
|
||||
-- Nostr-native identity: a user is keyed by pubkey_hash (peppered), an optional
|
||||
-- nostr_pubkey, and an optional reserved username. No platform-login columns.
|
||||
-- pubkey_hash and seed_fingerprint are stored HMAC-peppered (the pepper lives in
|
||||
-- config); UNIQUE constraints are on the peppered values. FK ON DELETE clauses
|
||||
-- support self-service erasure. Requires PostgreSQL 13+ (gen_random_uuid).
