feat: enable a2a-sdk 1.x by widening the dependency constraint

google-genai-bot · copybara-github · commit b46dd136aafe · 2026-07-09T03:36:17.000-07:00
Widen the a2a-sdk dependency constraint to &gt;=0.3.4,&lt;2 (both the a2a and test
extras) and re-lock so the ADK A2A integration resolves to a2a-sdk 1.x by
default while still supporting 0.3.x. The dual-version CI added in the parent
change keeps the compatibility shim verified against both SDK majors.
