Rewrite Go CLI in Rust

[phillipleblanc]

Summary

Complete rewrite of the Go CLI (bin/spice/) in Rust (bin/spice-cli/). This unifies the CLI with the spiced runtime codebase.

What's Included

All 27 commands implemented with full feature parity:

• Core: version, status, run, sql, init, install
• Data Inspection: datasets, catalogs, models, pods, workers
• Operations: refresh, upgrade, acceleration, add, connect, dataset
• Authentication (login + 7 subcommands): Spice.ai, Dremio, S3, Postgres, Snowflake, Databricks, Delta Lake, Spark
• Cloud (18 subcommands): login/logout/whoami, apps CRUD, deployments, logs, secrets, link/unlink, regions, images, api-keys
• AI/ML: chat (streaming SSE), nsql, search, eval
• Infrastructure: cluster tls init/add, trace

Technical Approach

• CLI Framework: clap with derive macros
• Error Handling: SNAFU with centralized Error enum
• Async: tokio runtime
• Table Output: comfy-table via TableOutput struct
• HTTP: reqwest client via RuntimeContext
• Streaming: futures::StreamExt for SSE (chat command)
• Certificates: rcgen with x509-parser for TLS certs

Next Steps

• Integration tests using assert_cmd crate
• Feature parity verification against Go version
• Cross-platform CI builds (Linux/macOS/Windows)
• Documentation updates
• Deprecation plan for Go CLI
