Feature Request: Add `info` Subcommand to Display Benchmark Metadata

[benecke2019]

Background

Currently, the kaprese benchmark CLI provides several useful subcommands:

• list: to show all benchmarks
• prepare: to pull or build benchmark images
• cleanup: to remove benchmark data

However, users cannot easily inspect detailed metadata of a single benchmark (e.g., image tag, language, OS, workdir, availability) without running list -d, which lists all benchmarks and may take extra time or viewing ~/.kaprese/benchmark/$benchmark.json .
This makes it inconvenient to check a specific benchmark's configuration before preparation or execution.

---

Proposal

Add a new subcommand:

kaprese benchmark info $benchmark

Example Behavior

Command

kaprese benchmark info flex-1

Expected Output:

Benchmark: flex-2
