Release v0.3.0

Bumps version to 0.3.0 and prepares the changelog.

What's in this release

• OTel tracing — withToolSpan() wraps every tool execution; suppresses diagnostic output on stdio
• Sublevel llms.txt resources — all 5 resources now point to product-level indexes instead of the broken root file
• get_mapbox_docs_index_tool — model can autonomously fetch any product's doc index without manual resource attachment
• Replace Algolia search — search_mapbox_docs_tool now uses cached llms.txt keyword search instead of shared Algolia quota
• docCache 5MB cap with warnings — raised from 2MB, logs warnings for large entries instead of silently dropping
• Dependency upgrades — tshy 4, vitest 4, TypeScript 6
