Fix version command to work without a profile

[pratik50]

Closes #121 and #122

• Make pb version and pb -v work with and without profile.
• Show the local version only; JSON output contains just the version field.
• Point users to pb status for server details.
• Align the PromQL agent catalog with the README’s --dataset syntax.

Summary by CodeRabbit

• Updates
  • pb version reports the client version only and works without an active profile or server connection.
  • Text output uses the format pb version <version>, with a leading v removed from the version.
  • JSON output contains only the normalized client version.
  • Use pb status for server and connection details.
  • Command descriptions now clarify the distinction between client version information and server status.

📝 Walkthrough

Walkthrough

The pb version command reports the local client version in text or JSON. It does not require a configured profile or contact the server. Documentation and command metadata direct users to pb status for server and connection details.

Changes

Client version and command catalog

Layer / File(s)	Summary
Client version behavior cmd/version.go, cmd/agent.go, README.md, cmd/version_test.go	pb version trims a leading v and outputs only the client version. JSON contains only the normalized version field. The command works without a usable profile. Documentation and metadata direct users to pb status for server and connection details. Tests cover text and JSON output with configured and missing profiles.
PromQL dataset arguments cmd/agent.go	The PromQL labels, label-values, and series catalog entries use --dataset; the series entry lists --match before that flag.

Explanation

Most changes support issue #121, including version documentation, the version catalog entry, and version tests. However, cmd/agent.go also changes unrelated PromQL catalog entries for labels, label-values, and series, including dataset selection and argument ordering. The linked issue and PR objective do not require these catalog changes.
