Temp title from idea snippet, skip placeholder titles in deep research

Project creation:
- Title auto-generated from idea's first ~80 chars (word boundary)
- Fallback: "Untitled Project" if no idea

Deep research:
- Skip placeholder titles (ending with "...", "Untitled Project", etc.)
  when building research query — use idea content instead
- Also reads "idea" field as fallback for "research_idea"
