Embedded Agent Toolkit 0.11.1
Adds optional board-registry 0.1.0 integration. The v2 component catalog keeps baud, BLEA, and embedded-debugger as the default core set; use --include-optional board-registry for a four-component cold install and v2 lock. This patch also makes Windows lock-path tests compare file identity across long and 8.3 path aliases. v0.11.0 was not released because its Windows CI test failed.
