Composite: list/browse the TELA apps discovered on-chain (each with its dURL, name, SCID, and doc count) — answers "what TELA apps exist?" without any external indexer. Powered by an in-process scan of the newest chain contracts.
When to call: when a user wants to explore or search the TELA ecosystem ("what TELA apps are there", "show me TELA games", "is there a TELA app about X"), or to find a SCID when they do not know the exact dURL. For an exact dURL use dero_durl_to_scid; to inspect a specific SCID use tela_inspect.
Input Requirements:
- `query` is OPTIONAL. Case-insensitive filter matched against dURL and name (e.g. "chess", "vault").
- `limit` is OPTIONAL (default 50, max 200).
Output: `{ query, total_matched, returned, truncated, apps:[{ scid, durl, name, install_height, doc_count }], index_meta, narrative, related_docs }`. The first call triggers a ~10s one-time discovery scan (cached afterward). `index_meta` discloses how much of the chain was scanned so the answer's coverage is transparent.
