Studio: harden Deep Research synthesis budget, prompt shielding, and message protection
- research_runs: split the synthesis evidence budget evenly across notes so a small context still keeps a slice of every research step instead of dropping the later steps after the earliest ones fill the budget. - research_runs: shield the research question and approved plan before placing them in the decision and synthesis prompts, so a closing delimiter in either cannot escape its block and inject sibling sections. - research_runs: redact bearer authorization tokens from public search queries. - studio_db: include attachments in the research-message change check and guard direct attachment deletion, so server-managed research prompts and responses cannot be mutated through the attachment paths. - chat_history: map the protected-message conflict on attachment deletion to 409.
