v0.5.20 — Context influence, easier agent control, private-deployment SSO

Highlights

• See where Context Tree guidance changed agent work: the Context tab now surfaces agent-reported influence, ranks cited nodes, and lets you filter the activity feed to influence events.
• Create and manage agents with less navigation: choose an online computer and runtime in one flow, switch agents from the Agent Detail breadcrumb, and remove other speakers from a chat from their identity card.
• Private deployments can require OpenID Connect SSO with PKCE, discovery/JWKS validation, and provider-aware login UI.

Notable fixes

• BYO Context workflows now preserve the exact installed CLI channel and pass the local GitHub identity through write-worktree setup, avoiding channel mismatch and authorization failures.
• Client recovery quarantines timed-out suspend handlers instead of letting stuck provider callbacks block future work, while SCM follow authority is more stable.
• Markdown rendering keeps a stable default renderer, and Chat Summary lead lines no longer receive unintended bold styling.

Compatibility

• Clients older than v0.5.12 are no longer supported. Upgrade older computers before using this release.
• Web and Server now assume same-version deployment; deploy them from the same Docker image.
