feat(node): Update vercel ai integration attributes

[AbhiPrasad]

Make changes to the Vercel AI integration as per https://www.notion.so/sentry/Agent-Monitoring-SDK-differences-21c8b10e4b5d80bcab51f72ae1418ea8

AI summary:

Key Improvements:

1. Eliminated duplicate attributes - Tool call and prompt attributes are now renamed instead of duplicated
2. Added tool input/output support - New gen_ai.tool.input and gen_ai.tool.output attributes
3. Auto-sets tool type - Automatically adds gen_ai.tool.type: 'function' for tool calls
4. Better OpenTelemetry compliance - Cleaner attribute mapping following semantic conventions

Technical Changes:

• Uses renameAttributeKey() consistently instead of duplicating attributes
• Removes old ai.* attributes after creating new gen_ai.* ones

🙌 thx for the quick changes!

Bug: Span Attribute Modification Bug

The processToolCallSpan function incorrectly uses renameAttributeKey to modify a local attributes object, which is a snapshot of the span's data (from spanToJSON(span).data). This prevents the gen_ai.tool.name and gen_ai.tool.call.id attributes from being set on the actual span, unlike the previous direct span.setAttribute() calls. This also creates an inconsistency with other attributes correctly set on the span, and impacts the span's name update which relies on the gen_ai.tool.name attribute.

packages/core/src/utils/vercel-ai.ts#L118-L120

sentry-javascript/packages/core/src/utils/vercel-ai.ts

Lines 118 to 120 in c4f69a3

	span.setAttribute(SEMANTIC_ATTRIBUTE_SENTRY_OP,'gen_ai.execute_tool');
	renameAttributeKey(attributes,AI_TOOL_CALL_NAME_ATTRIBUTE,'gen_ai.tool.name');
	renameAttributeKey(attributes,AI_TOOL_CALL_ID_ATTRIBUTE,'gen_ai.tool.call.id');

Fix in Cursor
