Architecture reframe: rename triad/Stoa/Logos/Agora → Passepartout

- Renamed ideas/stoa/ → ideas/passepartout/, all stage files prefixed passepartout-
- Renamed triad-index/overview/systemic-effects → passepartout-* under passepartout/
- Renamed ideas/agora/ → ideas/passepartout-social-protocol/, stripped agora- prefixes
- Merged overview and environment pages into architecture; deleted 3 redundant files
- Renamed growth-strategy → enterprise-growth-strategy
- Renamed alternative-growth-social-first → social-growth-strategy
- Removed all Greek names: Stoa, Logos, Agora as product names
- Updated 50+ files of cross-references to new naming
- Kept org-id UUIDs intact throughout
