• [docs] Update getting-started with permissions and :client-name #22 — [docs] Update getting-started with permissions and :client-name — already a docs PR, no further action needed
• feat: add :client-name to session config (upstream PR #510) #21 — feat: add :client-name to session config — already documented in API.md, CHANGELOG, and getting-started.md
• Fix permission denial keyword types and pin examples to gpt-5.2 #18 — Fix permission denial keyword types and pin examples to gpt-5.2 — already documented in CHANGELOG and API.md

 ### Changed
 - MCP local server example now passes `:on-permission-request copilot/approve-all` (required for MCP tool execution under deny-by-default)
+- Examples now use `claude-haiku-4.5` as the default model for non-streaming queries (faster and cheaper for demonstrations); streaming examples retain `gpt-5.2`
 
 ### Fixed
 - Permission denial result `:kind` now consistently uses keywords (not strings) in default handler responses, matching specs and `approve-all` behavior
