refactor(api): collapse DataSchema builder/built distinction and remove DT.Meta

[johngeorgewright]

DataSchema now exposes its parser records as public readonly fields and is passed directly to Data.create() — the separate .build() step and the BuiltDataSchema interface are gone. The DT.Meta indirection is also removed: Data<$ extends DataSchema = DataSchema> indexes the schema directly using camelCase keys that mirror the runtime object ($['payloadParsers'], etc.), so there is one shape for both type-level and value-level access.

TargetingPredicates is decoupled from the old Meta shape, Data exposes a schema getter, and downstream packages (server, client, fs, explode, json-schema, date-range) are updated to the new generic.

BREAKING CHANGE: .build(), BuiltDataSchema, DT.Meta, and DT.EmptyMeta have been removed.

Migration:

• Drop .build() calls; pass the DataSchema to Data.create() directly.
• Replace $ extends DT.Meta with $ extends DataSchema.
• Rename indexed access keys from PascalCase to camelCase: $['PayloadParsers'] → $['payloadParsers'] $['TargetingParsers'] → $['targetingParsers'] $['QueryParsers'] → $['queryParsers'] $['FallThroughTargetingParsers'] → $['fallThroughTargetingParsers']
• Replace DT.Any with DataSchema in generic constraints where you previously used it as the "match any" bound.

Pull request overview

Refactors @targetd/api’s type model so DataSchema is passed directly to Data.create() (no .build() / BuiltDataSchema) and removes the DT.Meta indirection by indexing directly into the schema’s camelCase parser-record fields. Updates all downstream packages to the new generics and indexing keys.

Changes:

• Remove the DataSchema “builder vs built” split; Data.create() now accepts DataSchema directly and Data exposes a schema getter.
• Replace DT.Meta/PascalCase indexed-access types with DataSchema/camelCase keys across server/client/fs/explode/json-schema/date-range.
• Update docs/tests/examples to drop .build() and align with the new schema-driven generics.
