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

 The self-driving threshold: the system can synthesize and load its own FPGA microcode or Tensix dispatch programs from within the running Lisp image. The system profiles its own gate verification latency, proposes a new microcoded instruction for the hot path, compiles RISC-V assembly from ACL2-verified specifications, loads it via PCIe DMA from within SBCL, benchmarks it — and rolls back if slower.
