Add OpenCode Companion plugin (#286)
* Add OpenCode Panel plugin Introduce initial implementation of the OpenCode Panel plugin. This commit includes: - Bar widget for status and quick actions. - Chat panel with session selection, message history, and input. - Background service for OpenCode server management, SSE event handling, and state persistence. - Plugin configuration, documentation, and internationalization. * Refine session chooser UI layout Remove an unnecessary spacer and apply top-justification to improve vertical alignment. Add a subtle background fill to the session list. * Introduce session search in chooser Enable live filtering of sessions in the chooser. Matches against title, slug, ID, and directory. Search is case-insensitive. * Support multi-question agent requests and clear composer Implement multi-question agent replies by accumulating choices locally. A "Submit" button becomes enabled only after all questions are answered. The chat composer clears its text after sending by updating its key, forcing the UI to re-render an empty input field. Updated translations for send hints and question submit button. * Add UI mode setting for compact layout Introduce a `ui_mode` setting (Full/Compact) that dynamically adjusts panel layout. Compact mode reduces padding, font sizes, and gaps, hiding some secondary details to minimize the panel footprint. Layout metrics recompute on every render based on this setting. * Delete opencode-panel * Update thumbnail.webp * Render chat messages newest-first Newest message shows at top. Scrolling down reveals older messages. This avoids scroll offset resets on re-mount in older shell APIs. Thinking bubble now appears above the newest message. * FEAT: Add panel layout setting Provide option for panel to fill right side or appear compact near click. Introduces a new panel entry for the "fill right" mode. * Rename plugin to OpenCode Companion Update plugin ID, panel entries, IPC commands, and state paths. * Only send model override when known Stale default_model now falls back to no override instead of failing every turn. Warn when configured default unavailable. * Update service.luau * fix(opencode-companion): secure terminal open, publish MCP status, respect auto_start - Shell-quote host and session id in the "open in terminal" command so a crafted server_host cannot inject extra shell commands - Publish opencode.mcp_status and render it as a collapsible footer (previously declared but never observable) - Honor auto_start: skip managed-server start on load when set to false - Fix broken thumbnail link in README (assets/thumbnail.webp -> thumbnail.webp) * fix Terminal command injection,MCP status publication and UI
