Summary:

Flips 2 targets in xplat/executorch/extension/android to
abi_generation_mode = "source_only" (clean flip, comparator 0 on
both). Causation check: the single consumer-build failure
(etu2net_debug, missing aiplatform inference segmentation interface on
the stub classpath) reproduces identically with the flip reverted, so
it is a pre-existing gap unrelated to this change, not a regression.

Validation per target: buck2 build of default, class-abi and
source-only-abi variants green; KOSABI_APPLICABILITY_REPORT_V2 silent;
widened six-leg compareAbi reports 0 differences; KmDump shows 0
public member diffs; direct consumers build 239/241 with the sole
failure proven pre-existing as above.
