chore(release): 0.21.0 coordinated MINOR (npm/PyPI/NuGet 0.21.0 · Maven 7.21.0)

The pre-1.0 breaking slot, carrying three changes that make previously-valid
metadata fail to load:

  1. Assembly origins (aggregate/computed/collection/first) are illegal on an
     object.value-hosted field -- ERR_SUBTYPE_RULE_VIOLATION. origin.passthrough
     stays legal there; on a value it is FR-015 parameter lineage, not assembly,
     and retiring it would have silently dropped the
     ERR_PASSTHROUGH_TYPE_MISMATCH check on stored-proc arguments. (#210)
  2. source.rdb @ROLE accepts only primary|replica; index/cache/publish/mirror
     retire to reserved-not-registered. No port ever built the role-routing
     dispatch they anticipated -- every read was an equality test against
     primary. (#212)
  3. A payload's nested field.object @objectref must target an object.value.
     TypeScript, C# and Python previously accepted a non-value target AND
     emitted code from it, so this is a genuine third break.

MINOR rather than PATCH on the mechanical argument: pre-1.0 a caret range
^0.20.x resolves <0.21.0, so a patch would be auto-adopted on a routine update
and adopters' metadata would stop loading with no deliberate action. MINOR makes
them opt in, which is what the pre-1.0 breaking slot exists for.

The migration path is additive: @payloadRef/@responseRef now accept a sourceless
object.projection, so a payload that was assembling values re-hosts as a
projection and keeps its origins. Guide:
docs/features/migrations/value-assembly-origins-and-source-role-shrink.md

All four registries ship changed product code this cut.
