docs(arch): Add ARCHITECTURE.md and CLAUDE.md, init repo

Bring the Blanton Tera Term TTL test suite under version control and
document how the pieces fit together.

- ARCHITECTURE.md: A/B/C script roles, host-to-DUT-to-FPGA data path,
  config/settings/profile data models, PCIe AER + EDAC topology table,
  10 key constraints, and 6 development phases derived from the
  Status_20260814 spreadsheet's On-Going items
- CLAUDE.md: stack, smoke-test commands, conventions, and the hardware
  footguns (per-unit BDF, VSPI vs VI2C timing, repeated START,
  STORE_USER_ALL, ARB_LOST false positives)
- secret/: gitignored credential store with README + .example template,
  so the DUT login stops living in 1_Blanton_Script_A.ttl
- .gitignore: secret/*, For_AI/, *.log, publish/, *.DSN
