test: add e2e test for error handling when MCP servers are unavailable

[sboorlagadda]

Problem

There are no e2e tests covering how the mirroring subsystem behaves when an MCP server is unreachable, times out, or returns errors.

Proposed Solution

Add e2e tests in tests-e2e/ that verify graceful error handling when:

• MCP server is unreachable (connection refused)
• MCP server times out
• MCP server returns malformed responses

Files

• tests-e2e/
• src/stuntdouble/mirroring/

Difficulty

Medium
