fix(agent): surface active extension state to the LLM

* feat(cli): add ironclaw models subcommands (list/status/set/set-provider)
  Implements  model management CLI (part of #83):
  - `models list [provider] [--verbose] [--json]` — list providers; fetches
    live model list from the provider API when a specific provider is given
  - `models status [--json]` — show active provider/model
  - `models set <model>` — set default model with validation
  - `models set-provider <id> [--model <name>]` — set provider with alias
    normalization
  - fix conflicts

* fix(deps): update tar to 0.4.45 (RUSTSEC-2026-0067, RUSTSEC-2026-0068)
