Fix hardcoded absolute paths and missing mock in JS tests

[Copilot]

JavaScript tests were failing due to hardcoded /tmp/gh-aw/actions/ paths breaking TypeScript compilation and incomplete test mocks missing the addHeading method.

Changes

• Fixed require paths in JS modules: Replaced absolute /tmp/gh-aw/actions/ paths with relative ./ imports in add_comment.cjs and noop.cjs
• Fixed test mock: Added missing addHeading method to core.summary mock in missing_tool.test.cjs

-const { loadAgentOutput } = require("/tmp/gh-aw/actions/load_agent_output.cjs");
+const { loadAgentOutput } = require("./load_agent_output.cjs");

-summary: { addRaw: vi.fn().mockReturnThis(), write: vi.fn().mockResolvedValue() },
+summary: { addRaw: vi.fn().mockReturnThis(), addHeading: vi.fn().mockReturnThis(), write: vi.fn().mockResolvedValue() },

All 109 test files now pass (2238 tests).
