Add project-scoped MCP server configuration with global/project merge semantics, a richer settings UI, and chat composer access. Introduce MCP config scanning plus project-aware status/detail/log/apply APIs while preserving the raw JSON editor. Strengthen MCP runtime handling for dotted tool names, timeouts, status accuracy, and project-aware tool execution, with focused regression coverage.
Preserve MCP image, audio, and resource tool results instead of collapsing non-text responses into an empty textual result. Images and image resources now flow into raw history as data URL attachments, while audio and non-image binary resources are saved as artifacts with normalized paths.
Extract shared media artifact helpers for base64 validation, image data URLs, decoded-size checks, artifact saving, MIME normalization, and safe filenames. Reuse the shared helpers from MCP, browser connector, and computer-use artifact paths, and add focused regression coverage.
