v0.34.0

[0.34.0] - 2026-07-14

Bug Fixes

• Recognise DECIMAL(p,s) sqlType override -> ErmDataType.Decimal (erm)

Features

• UuidRepresentation option — kotlin.uuid.Uuid columns (erm-exposed)- DateTimeRepresentation option — kotlinx.datetime columns (erm-exposed)- «Column».fkEntity/fkAttribute — column-level FK override bypassing association derivation (erm)

Other

• ERM external enum type: enumType tag on ermMappingProfile «Column», ErmDataType.Enum.externalFqName, emitter support

Adds a retrofit escape hatch for ERM enum columns that must reference an
already existing Kotlin enum (e.g. a type shared across an RPC boundary)
instead of generating a fresh local enum class:

• ermMappingProfile «Column»: new optional enumType tag (ErmProfileNames.TAG_ENUM_TYPE)
• ErmDataType.Enum: new externalFqName field; null preserves the original
  locally-generated enum class behaviour
• ErmExposedEmitter: imports and references the external enum type instead
  of emitting its own enum class when externalFqName is set
• ErmModelDslPrinter / ErmScriptRenderer: round-trip the new field
• UmlErmTypeMapper: also recognises an explicit VARCHAR(n)-shaped sqlType
  override (case-insensitive), mapping it to ErmDataType.Varchar(n) instead
  of falling through to ErmDataType.Custom
• Test coverage for the new mapping and emitter paths- CHANGELOG + version bump (v0.34.0)
