Release on mcp, hotfix

[Copilot]

Pull request overview

This PR is a hotfix release on the MCP (Model Context Protocol) that includes two main areas of enhancement: (1) extending the media placeholder pattern to support both formats with and without the base64, marker, and (2) adding a new supports_browser capability flag to the model catalog system.

Key Changes

• Updated media placeholder regex pattern to accept both data:image/jpeg;jan_xxx and data:image/jpeg;base64,jan_xxx formats across media-api and llm-api services
• Added supports_browser boolean field to model catalogs with full database migration, domain model, API, and repository support
• Enhanced chat message handling to support flexible content formats from different clients (OpenAI format and browser-mcp format)
• Improved tool message handling by properly setting tool_call_id and using appropriate content types
• Removed verbose error logging in streaming operations (simplified to silent error suppression)

• The variable chunksReceived is incremented twice for data lines: once at line 293 for every line received, and again at line 328 only for lines that have a data prefix. This results in data chunks being double-counted. If the intention is to count all lines including non-data lines, remove the increment at line 328. If the intention is to count only data chunks, remove the increment at line 293.

Since Go 1.21, the min function is built into the language. This custom implementation can be replaced with the built-in min function. The codebase is using Go 1.25.0, so the built-in function is available. Note that this same helper function is duplicated in multiple files.

Suggested change

	// min returns the minimum of two integers
	func min(a, b int) int {
	if a < b {
	return a
	}
	return b
	}
