- architect/AGENTS.md: update responsibilities, state transitions, vision
lifecycle, and execution sections to reflect read-only role and filer-bot
architecture (#764)
- lib/sprint-filer.sh: add filer_api_all() paginated fetch helper; fix
subissue_exists() and check_and_close_completed_visions() to paginate
instead of using fixed limits that miss issues on large trackers
- lib/sprint-filer.sh: fix extract_vision_issue() to look specifically in
the "## Vision issues" section before falling back to first #N in file
