+Pearl th-2b5f63: add `th cast models` — list live model groups
+exposed by the configured LiteLLM provider (e.g. llm.smoo.ai) via
+`GET /v1/models`.
+
+Useful for confirming deploys, debugging routing, and copying
+alias names. The default provider is the one backing the `default`
+routing slot (what `th routing show` highlights); pass
+`--provider NAME` to override on multi-provider setups.
+
+Flags:
+
+- `--provider NAME` — override the provider id (default: the
+  provider backing the `default` routing slot).
+- `--filter PATTERN` — case-insensitive substring filter on
+  model ids.
+- `--json` — emit `{"data":[{"id":"..."}]}` for scripting.
+
+The parser is tolerant of LiteLLM responses with embedded ASCII
+control bytes (we strip 0x00-0x1F before strict JSON parsing) and
+of truncated responses (a byte-scan fallback recovers any
+complete `"id":"NAME"` entries). When the strict and lossy
+counts disagree, the footer surfaces a `!` warning so deploys
+returning partial bodies don't fail silently.
+
+Exits 2 if no provider is configured (`run th auth login`), and
+prints the status code + first 200 chars of the body when the
+provider responds non-200.
