Free-tier Zen models reject Responses requests with 403 FreeTierError
when client tools are present but the fingerprint quartet is missing.
Apply the fingerprint tools to every OpenCode request, canonicalise
case variants of the quartet (Bash->bash) without duplication, and
restore the caller's original spellings on the response side via a
request-local WeakMap threaded through the existing toolNameMap.
- Force stream:true and cloak decoy tools (bash, read) for OpenCode free tier
- Support connection testing for opencode in testUtils
- Expand error message slice limits in auth and ping to preserve workspace link
- Add concise China region link chip in provider detail page

Follow-up to the canonical-session fix: with no explicit session,
every request minted a fresh x-opencode-session, and upstream free-tier
quota is accounted per session. That burns through quota and surfaces
as 429 FreeUsageLimitError with growing reset-after delays, while the
real CLI reuses one long-lived session per conversation.
- Stable canonical session per downstream identity (connectionId, else
auth-header hash, else shared default), evicted after
MEMORY_CONFIG.sessionTtlMs like the other session stores.
- Deterministic x-opencode-request per message (stable across retries,
like the CLI user message id); valid downstream ids preserved.
- 6 more unit tests (22 total).
OpenCode upstream validates free-tier requests: User-Agent must be opencode/<version> (>= 1.17.0) and x-opencode-session must match canonical ses_ format. Default OPENCODE_UA to opencode/1.18.31, generate canonical descending session IDs, provide deterministic foreign session translation, and isolate credentials per-request.
