release: v1.15.1

core: clarify postinstall error message when binary is missing
Users installing with pnpm or --ignore-scripts now see a clear explanation of why the native binary is missing and exact steps to fix it. The shell script wrapper provides more actionable guidance than the previous Node.js fallback that only suggested running the postinstall script without context about why it wasn't run automatically.

+## User-Facing Rendering
+
+HTTP serialization and user rendering are separate boundaries. The server
+should send structured public errors; CLI and TUI code should format those
+structures through one shared formatter.
+
+For SDK calls using `{ throwOnError: true }`, the generated client may wrap the
+decoded response body in an `Error`. The original body should remain available
+under `error.cause.body`; `FormatError` is the right place to unwrap and render
+that body. TUI aggregation helpers should call `FormatError` first, then fall
+back to generic `Error.message` / string rendering.
+
+When several parallel startup requests fail from the same underlying issue,
+group identical rendered messages and list the affected request names once.
+For example:

+```text
+Configuration is invalid at /path/to/opencode.json

 Unknown `500` responses should log full details server-side with

+The config startup regression in #27056 is the failure mode this rule is meant
+to avoid: a user-authored invalid `opencode.json` crossed the HttpApi boundary
+as a defect, so middleware replaced a useful `ConfigInvalidError` with a safe
+generic `UnknownError`. The compatibility fix is to preserve config parse and
+validation errors as client-visible `400`s. The target architecture is better:
+config loading should fail on the typed error channel, config HTTP handlers
