v0.8.3

Added

• OpenCode agent: first-class support for the OpenCode CLI runtime — Docker
  image and entrypoint, runtime adapter, agent registry registration, frontend
  configuration, ProPR CLI command, model-alias and GitHub-label resolution,
  live-details/task-stream parsing, and dynamic model discovery.
• Vibe (Mistral) agent: new Mistral-backed agent with API-key configuration,
  shared-agent registry entry, runtime adapter, and Vibe branding.
• CLI control plane: manage the local Docker stack and relay GitHub tokens
  from the @propr/cli package; CLI-driven setup is now the primary path.
• User whitelist gating: dashboard/CLI access and issue-label triggers can be
  restricted to a configured set of users.
• Background GitHub session refresh: expired GitHub session tokens are now
  refreshed in the background (resolves the logout redirect loop).
• Summarization fallback: configurable fallback model with quota-aware retry
  so repository indexing survives provider rate limits and outages.
• Claude Fable 5 model support.
• Offline full-text documentation search.
• Extensive documentation: Web UI Guide, Agent Tank usage-tracking guide,
  Secure VPS Deployment tutorial (with optional Cloudflare Zero Trust layer),
  Repository Best Practices guide, CLI control-plane docs, and a rebuilt docs
  home page.

Changed

• Renamed the Gemini agent integration to Antigravity across runtime, Docker
  images, entrypoints, credentials, parsers, model IDs, and documentation; added
  support for the Antigravity CLI runtime.
• Modernized the header system-status menu and compacted the Settings page into
  horizontal rows with numeric inputs.
• Cleaned up dashboard stats tables and humanized model names.
• Codex planner now caps and budgets prompt/context size using the usable input
  window, with priority-based context packing and reduced metadata overhead.
• Epic chains now require a child PR merge before starting the next issue.
• Docker Hub metadata is synced on release (non-blocking).
• Documentation defaults to Claude Opus 4.8 in examples and gives the CLI equal
  footing in setup tutorials.

Fixed

• Summarization: stop prompt-too-long failures masquerading as parse errors;
  improve fallback parsing and reliability; scope batch limits by model.
• Indexing: recover from partial summarization failures without a full reindex;
  dedupe prioritized jobs; refresh summarization config between batches; cap
  repository summary batch size/file count; skip generated capture artifacts.
• Pricing: correct OpenRouter slugs for gemini-3.1-pro, nemotron-3-ultra, and
  native opencode-go/* models.
• Antigravity: deliver prompts via stdin to avoid E2BIG, use CLI display names
  for --model, estimate implementation tokens from the full transcript, and
  fix token usage / log filtering.
• Vibe: numerous runtime fixes for live-log streaming, transcript parsing,
  credential loading, container permissions, and token/cost reporting.
• TaskWatcher: fix EMFILE error by switching to polling.
• Metrics: stop infinite task-analysis recursion in the analysis processor.
• Fix default GitHub bot username and use the ProPR app bot for system commits.
