fix: update test agent names from "build" to "builder" and fix registry test

- Agent config keys in tests: build → builder (matches actual agent name)
- Read test context: agent "build" → "builder"
- defaultAgent tests: disable all primary agents (builder, analyst, validator, migrator, plan)
- Registry test: handle cowsay import failure gracefully in sandboxed envs
