v0.6.0

Added

• prost-protovalidate-build — Builder::runtime_bridge. Opt-in mode
  (buffa backend only) that gives messages the compile-time generator cannot
  cover — CEL rules, predefined CEL, or shapes otherwise routed to the runtime —
  a generated impl Validate that encodes the message to protobuf wire bytes and
  validates it through the runtime Validator, reusing the full engine
  (including the CEL interpreter) instead of a cargo:warning skip or a hard
  error. One library now emits compile-time validators for the entire
  buf.validate rule surface against buffa-generated types: standard rules
  inline, everything else through the bridge — so the buffa path reaches the same
  coverage as the runtime Validator. Mutually exclusive with
  fail_on_runtime_only (returns the new Error::ConflictingOptions); the routed
  messages pull prost-protovalidate's reflect/cel features into the
  consumer, while standard-only builds keep the slim fail_on_runtime_only
  footprint.
• prost_protovalidate::bridge (feature reflect) — RuntimeBridge
  (from_fds / validate_wire) plus error_to_validation_error, the runtime
  surface the runtime_bridge generated code targets. Self-contained so the
  generated code references only ::prost_protovalidate::* (no direct
  prost-reflect dependency in the consumer).
• string.protobuf_fqn / string.protobuf_dot_fqn well-known string rules
  (re-added upstream in protovalidate v1.2.0) — validate that a string is a valid
  Protobuf fully-qualified name, without or with a leading dot. Available on both
  the runtime Validator and the compile-time backend, and exposed as
  validators::is_protobuf_fqn / is_protobuf_dot_fqn.

Changed

• BREAKING (prost-protovalidate-types): Synced validate.proto to upstream
  protovalidate v1.2.2 (from v1.1.1), re-adding the string.protobuf_fqn /
  string.protobuf_dot_fqn rules removed in 0.3.0. The generated
  string_rules::WellKnown enum gains ProtobufFqn and ProtobufDotFqn
  variants — breaking for exhaustive matches on that enum (also reachable
  through prost_protovalidate::types), hence the 0.6.0 bump. The conformance
  harness pin moved to v1.2.2; full conformance retained — 2872/2872 tests
  pass (0 expected failures).
