- Revert leader workspace override: leader keeps personal workspace as
default, team workspace accessible via ToolTeamWorkspaceFromCtx
- Auto-copy: when leader creates team_tasks, scan subject+description
for file paths → copy from personal to team workspace so members can
access them
- Safety: Lstat (reject symlinks), 10MB size cap, .env excluded from
allowed extensions, path traversal blocked
- Prompt hint: clarify members can only access team workspace files,
referenced files are auto-copied
