Pull request overview

Refactors StreamNative Cloud (SNCloud) MCP tools/prompts to rely more on session-bound organization/context, and introduces reusable tool/prompt constructors with accompanying tests and doc updates.

Changes:

• Replaced inline SNCloud tool/prompt definitions with reusable constructor functions and exported handlers.
• Updated SNCloud resource tools to resolve organization preferring the active SNCloud session (with fallbacks).
• Added docs updates and new unit tests covering constructors and organization resolution behavior.

• HandleSNCloudLogs returns a non-nil Go error when the SNCloud session is missing. For MCP tool handlers in this repo, missing sessions are typically surfaced as mcp.NewToolResultError(...) with a nil error so clients get a structured tool error instead of an internal handler failure.

	// Get log client from session
	session := context2.GetSNCloudSession(ctx)
	if session == nil {
		return nil, fmt.Errorf("failed to get StreamNative Cloud session")
	}
