[Workers] Document local observability and AI agent integration in Local Explorer

[nevikashah]

Summary

Adds observability and AI agent documentation to the Local Explorer page. This covers the new traces and logs features that ship with wrangler@4.114.0, and updates the AI agent section to reflect the new Wrangler agent detection behavior.

Changes:

• New Observability section with Logs and Traces subsections
• Updated AI agent section (renamed from "AI coding agents") to describe Wrangler's agent detection hint
• Added <Steps> wrapper to the setup procedure with Wrangler/Vite plugin distinction
• Fixed unused component imports, capitalization ("SQL Studio"), and broken link in the observability index page
• Added a LinkCard on the Workers observability index pointing to Local Explorer

Documentation checklist

• The change adheres to the documentation style guide.

Review

⚠️ 1 warning, 💡 1 suggestion found in commit 0304bef.

👉 Fix in your agent 👈

Fix the following review findings in PR #32339 (https://github.com/cloudflare/cloudflare-docs/pull/32339).

Before making changes, review each finding and present a brief summary table:
- For each finding, state whether you agree, disagree, or need clarification
- If you disagree (e.g. the fix requires disproportionate effort for minimal benefit,
  or the finding is factually incorrect), explain why
- If you need clarification before deciding, ask those questions
- Then share your plan for which issues to tackle and in what order

After triaging, follow this order:
1. Post a comment on this PR for any findings you are skipping, with the finding ID and your reasoning.
2. Then commit the fixes for the legitimate findings.

The comment must come before the commit — the bot reads PR comments when a new
push triggers a review, so skip comments posted after the push will be missed.
