fix: pin a2a-sdk<1.0 to keep a2a.server.apps import working

Browse Source 
a2a-sdk 1.0.0 restructured the package and removed a2a.server.apps,
which main.py imports directly for A2AStarletteApplication. The
current >=0.3.25 constraint resolves to 1.0.0 on fresh installs and
the runtime crashes at startup with ModuleNotFoundError — which is
exactly what bit production workspace EC2 instances provisioned on
2026-04-20.

Bump to 0.1.3 and pin <1.0 until we're ready to migrate to the 1.x
import paths. Companion fix in molecule-controlplane PR #174 pins at
pip-install time; this PR fixes the upstream package so other callers
don't re-hit the same trap.
