jenkins-debug

[skaile-development] Debug a recently failed Skaile deployment on Jenkins. Defaults to the skaile_platform job; pass target=store to debug the skaile_store job instead. Reads the job over the local SSH tunnel (http://localhost:8090, anonymous read), finds the relevant build (last failed by default, or current/explicit), extracts the failure region from the console log, cross-references recent commits in skaile-dev around the build timestamp, and reports a structured summary with a fix hypothesis. Use when the user says "why did the deploy fail", "debug the jenkins failure", "what broke on jenkins", "the platform deploy is red", "the store deploy is red", "check the last platform-deploy", or otherwise asks about a Jenkins deployment failure.
