Add Rust CLI port

[etbyrd]

Summary

• Add an optional Rust CLI port with generated operation manifest, friendly command routing, auth/config handling, and the major task-oriented command groups.
• Add Rust packaging and install scripts for release-style archives while keeping rollout separate from the root npm package path.
• Add parity harnesses for command surface, bytewise help copy, generated request coverage, black-box Node-vs-Rust fixtures, packaged archive parity, live smoke entrypoints, and browser-launch trapping during parity tests.

Validation

• CI is rerunning on the current PR head.
• make rust-cli-full-check
• make cli-parity (2737 Node-accepted help spellings, 119/119 operations, 58/58 generated aliases, 119/119 generated command fixtures, 467 black-box cases)
• make cli-archive-parity (2737 Node-accepted help spellings and 467 black-box cases against both extracted primitive and prim archive binaries)
• make rust-cli-check-generated cli-command-surface-parity cli-operation-coverage
• node --check scripts/run-cli-parity.mjs
• node --check scripts/run-cli-help-sweep.mjs
• node --check scripts/generate-rust-cli-help-snapshots.mjs
• cargo build --manifest-path cli-rust/Cargo.toml --locked
• git diff --check

Heads-up on stacking: there are five open PRs based on rust-cli-port, all Greptile 5/5 or close, fixing parity gaps found by differential testing against the Node CLI:

• Rust CLI: complete usage-error exit-code coverage (exit 2, matching Node) #332 usage errors exit 2 (matching oclif)
• Rust CLI: match Node's API-error stderr shape; scope x402 hints to payments #333 API-error stderr flattened to match Node + x402 hints scoped to payments (+ macOS test-server flake fix)
• Rust CLI: honor NO_PROXY=* like the Node CLI #334 honor NO_PROXY=* (reqwest ignores it; undici honors it)
• Parity fixtures: assert output on 48 request-only generated-alias cases #335 output assertions + cross-compare for 48 request-only parity fixtures
• Rust CLI: preserve JSON key order in output, matching Node #336 serde_json preserve_order → stdout byte-identical to Node against live staging

Each force-push of rust-cli-port (three so far) invalidates all of them and costs a round of conflict surgery + re-review. Two easy options: pull these branches into your next snapshot before force-pushing (each is a clean delta on the current head), or ping before rewriting so the stack can be rebased in one pass. Happy to hand any of them over as patches if that's easier.
