v1.14.42

## Core

### Improvements

- Added HTTP API response compression for large non-streaming responses.
- Added the Scout agent for repo research, docs lookup, and dependency-source inspection.
- Added workspace sync so adapter-backed workspaces can be discovered and registered automatically.
- Added an interactive split-footer mode for `opencode run`.
- Simplified TUI keybinding config into a flat keybind format.
- Made duplicate worktree names fall back to the parent directory for clearer labels.

### Bugfixes

- Fixed HTTP API auth responses to match the previous wire format for empty authorize results and share errors.
- Returned structured validation errors from the HTTP API.
- Rejected invalid permission and question IDs in the HTTP API.
- Included auth challenges on typed HTTP API `401` responses.
- Fixed the HTTP API OpenAPI document route.
- Fixed detached sessions so they are claimed by the source project again.
- Forwarded `SIGINT`, `SIGTERM`, and `SIGHUP` correctly when running through the npm shim. (@chubes4)
- Allowed skills without descriptions to load correctly.
- Required auth on effect HTTP API root routes. (@RajvardhanPatil07)
- Kept tool ordering stable so tool lists stop reshuffling between runs.
- Made retry dialogs more specific to the provider and failure reason.
- Fixed Gemini reasoning controls so supported effort levels and small-mode defaults match the model.
- Fixed Anthropic Opus 4.5 reasoning effort options.
- Limited OpenAI deep research models to the reasoning level they actually support.
- Fixed GPT-5 reasoning variants so the exposed effort options match each model family.

## TUI

### Improvements

### Bugfixes
