Overview

• What does this change accomplish and why?
  • Adds UNISON_MCP_TIMEOUT environment variable to configure MCP tool call timeouts
  • Previously: hardcoded 60-second timeout with message "timed out after 1 minute"
  • Now: configurable timeout (in seconds) via env var, defaults to 60 seconds, message shows actual timeout value

Interesting/controversial decisions

• Env var is specified in seconds (not microseconds) for user convenience

Loose ends

None.

Final checklist

• PR title: "Add UNISON_MCP_TIMEOUT environment variable for configurable tool timeouts"
• Description is accurate
• No transcript changes needed - behavior is backward compatible
• No .cabal file changes
