Add Rust CLI port

[etbyrd]

Summary

• Add an optional Rust CLI port with generated operation manifest, friendly command routing, auth/config handling, payloads, payments, functions, wake, routes, search, and mail behavior.
• Add Rust packaging and install scripts for local release artifacts.
• Add parity harnesses for command surface, generated request coverage, help copy/flag comparison, black-box Node-vs-Rust fixtures, archive parity, and live smoke testing.
• Keep the rollout separate from the root npm package path.

Validation

• make rust-cli-full-check
• Post-rebase make rust-cli-check
• Post-rebase make cli-parity (340 black-box cases, 119/119 generated operations covered, 58/58 generated aliases covered)
• node scripts/run-cli-help-sweep.mjs --compare-flags --node-bin "node cli-node/bin/run.js" --rust-bin "./cli-rust/target/debug/primitive" (1130 Node-accepted command spellings checked)
• pnpm --dir cli-node exec biome check ../scripts/run-rust-cli-live-smoke.mjs ../scripts/run-cli-help-sweep.mjs
• Live production API smoke using a local key: 20 no-key cases, 30 authenticated read-only cases, and 1 real email send-and-wait case passed
• git diff --check
