Changelog

0.2.0

Casting/decoding a malformed prefixed ID whose slug contains characters outside the base58 alphabet (0, O, I, l, punctuation, …) no longer crashes with ArithmeticError/ArgumentError from erl_base58 — every malformed input now returns {:error, :invalid_prefixed_id} (or raises ArgumentError from the bang variants). This is the exact class a public URL parameter delivers to a cast path.

to_uuid/1 and to_uuid_string/1 — non-bang variants returning {:ok, value} | {:error, :invalid_prefixed_id}, for validating external input (HTTP params, etc.) at system boundaries.
to_prefixed_id/2 now also accepts a resource module as the second argument, resolving the prefix from the resource's prefixed_id DSL (avoids hard-coding the prefix string).

Removed decode_object_id/1. It was a redundantly-named twin of the new to_uuid_string/1; use to_uuid_string/1 (tagged tuple) or to_uuid_string!/1 (raising) instead.
to_uuid_string!/1 now raises ArgumentError for invalid input (previously could leak a MatchError).
Conversion failures now use tagged {:error, :invalid_prefixed_id} tuples instead of a bare :error.

PostgresExtension: drop LEAKPROOF from timestamp_from_uuid_v7/1. LEAKPROOF only matters when a function appears in a query crossing a PostgreSQL security barrier (RLS, security_barrier views), which Ash does not enable by default. Marking a function leakproof requires superuser, which blocks every managed Postgres provider (RDS, Cloud SQL, Heroku, Supabase, Neon, …). Defaulting to portable migrations is worth the lost optimizer hint. Users who actually need it can run ALTER FUNCTION timestamp_from_uuid_v7(uuid) LEAKPROOF; themselves as superuser.
