Symlink build dirs outside workspace to fix Copilot image limit

- Redirect build/, .dart_tool/, ephemeral/ dirs to ../testsAndMisc_builds/
- Add .jar, .dex, **/build/, **/.dart_tool/, **/ephemeral/ to .copilotignore
- Add horatio build dirs and .dart_tool to files.exclude/search.exclude
- Gitignore symlinks without trailing / (git treats symlinks as files)
