Merge pull request 'The controller takes mesh-sdk a7a1fbd3, so its composer gives build modules the node's CPU share (issue 1806, ADR 0553/0554 change B)' (#473) from fix/controller-sdk-cpu-share into main

The controller is the only composer, and its pin (10b6e202) predates mesh-sdk #95: without the bump the
build runtimes never get yields {priority idle, cpu-share} or MESH_BUILD_CPU_SHARE (ADR 0553, ADR 0554,
change B). The operator said yes to this one change of the frozen controller on 2026-10-26 15:54.

A composition at both pins over every node's assignment differs only in mesh-build-go, mesh-build-node and
mesh-build-image (the yields and the share word); every other composition is byte-identical. The SDK's
conformance capture moves with the pin, as testdata/beside/CAPTURED asks.

Research 072 (the controller, NATS-native): no piece moved; a pin bump the operator allowed.
