feat: add 9 missing MCP cartridges for full polystack replacement
Add cloud, container, k8s, git, secrets, queues, iac, observe, and ssg cartridges — each with Idris2 ABI (dependent type proofs + state machines), Zig FFI (C-ABI implementation), and V-lang adapter (REST/gRPC/GraphQL). BoJ server now has 13 cartridges covering all domains previously split across the polystack monorepo. Every cartridge enforces the 4 mandatory C-ABI symbols (init, deinit, name, version) and uses formal verification to prove safety properties at the type level.
