improvement(search): guide independent live searches and reads into one step

[waleedlatif1]

Summary

• Shared live-search guidance now tells MCP/tool clients that one search across providers returns one ranked list for the same question, and that independent searches and reads of different documents should be issued together in the same step
• Follows Anthropic's parallel tool use guidance: the model rarely batches independent calls unless prompted, and each extra step costs a full model round trip
• Companion worker change adds the same instruction to the Assistant prompt

Type of Change

• Improvement

Testing

Live-search tests (298) pass; lint, audits, docs manifest and type-check clean
