Subject: [PATCH] fix: include free OpenCode models without -free suffix in
 suggested models (#1535)

The "opencode-free" suggested-models filter only kept models whose id ends
in "-free", so free-but-unsuffixed models like `big-pickle` (routed via
open-sse/executors/opencode.js MESSAGES_MODELS) never appeared in the
import UI.

Extract the filters into a testable module and include a
KNOWN_FREE_OPENCODE_MODELS allowlist (big-pickle) alongside the "-free"
suffix check.
