feat(agents): add beta end call tool

[rosetta-livekit-bot]

Summary

• Add beta EndCallTool ported from Python for ending calls from a tool invocation.
• Add JobContext.deleteRoom() support and export worker credentials to child job env so room deletion works when options are passed programmatically.
• Export the new beta tool and add a changeset.

Testing

• pnpm --filter @livekit/agents build
• pnpm --filter @livekit/agents lint (passes with existing warnings)
• pnpm format:check

Notes

• pnpm --filter @livekit/agents api:check is currently blocked by API Extractor failing on existing export * as ___ syntax in dist/index.d.ts before checking this API surface.

🟡 providerTools getter exposes internal mutable array instead of returning a defensive copy

The ToolContext.providerTools getter at agents/src/llm/tool_context.ts:285 returns the internal _providerTools array directly, despite its JSDoc comment promising "A copy of all provider tools". This is inconsistent with the functionTools getter (which creates a new Object.fromEntries(...)) and the toolsets getter (which spreads into a new array [...this._toolsets]). External consumers can mutate the internal array (e.g. .push(), .length = 0), silently corrupting the ToolContext state and breaking invariants like equals(), hasTool(), and flatten().

Suggested change

	get providerTools(): ProviderDefinedTool[] {
	return this._providerTools;
	}
	get providerTools(): ProviderDefinedTool[] {
	return [...this._providerTools];
	}
