chore(release): 0.20.15 coordinated (npm/PyPI/NuGet 0.20.15 · Maven 7.20.15)

Coordinated across all four registries per the single-shared-patch policy — the
ERR_PROJECTION_INHERITED_SOURCE guard is a loader change, so every port ships it.

PATCH: it rejects a shape that produced no working artifact in any port (TS mounted
writable CRUD over a read-only view; Java and Kotlin skipped on their subtype gate;
Python on the resolved source kind; C# emitted nothing). Same class as
ERR_ENUM_EXTENDS_VALUES_CONFLICT (#246, 0.20.11) and ERR_DUPLICATE_SQL_NAME
(0.20.9): a defect-class rejection, not a break in working compat surface, so it
does not need the ADR-0035 §3 consolidation window and does not reset the quiet
clock.

Verified before promoting: all five ports green (TS 516 conformance / 2284 total,
Java 516, Python 495 conformance / 1541 total, C# 842 conformance + Codegen 342 /
Render 290 / Cli 46); RC published to `next` and installed externally, where the
guard fires correctly on a projection inheriting its source.
