Block the MCP servers and Plugins tabs in the chat customizations editor
when their respective access settings are disabled, including via
enterprise policy.

- McpListWidget watches `chat.mcp.access`; shows splash when value is
  `none`. If `policyValue === 'none'`, shows policy-locked message and
  hides the "Open Setting" button.
- PluginListWidget watches `chat.plugins.enabled` with the same
  user/policy distinction.
- Reuse `.mcp-list-widget` root class so the new `.mcp-disabled-state`
  CSS applies to both widgets via a single `.access-disabled` modifier.
- Add Dark/Light fixtures for both widgets in user-disabled and
  policy-locked states (8 new screenshots).

agentHost: show rich diffs when requesting write confirmations

Disabling walkthrough for web

…s-step

Remove extensions step from onboarding

Adds a pure helper shouldKickOffBackgroundSummarization that gates the
post-render background compaction trigger based on prompt-cache warmth:

- inline + warm cache (toolCallRounds.length > 0): jittered threshold in
  [0.78, 0.82) straddling the historical 0.80 edge.
- inline + cold cache: emergency kick-off at >= 0.90 to keep long-running
  sessions from hitting sync foreground compaction.
- non-inline: unchanged >= 0.80.

The rng is injected via a private field so tests are deterministic and
the warm-only jitter path is exercised without touching Math.random.

Follow-up to #310871: the sidebar entrypoint actions (Agents, Skills,
Instructions, Hooks, MCP Servers, Plugins) still called
selectSectionById after opening the editor, which deep-linked into
the section instead of showing the overview.

* Top-align editor/detail back button to match section arrow

The .editor-header has align-items: center and contains a multi-line title
(name + filename), causing the 26px back button to drift down when centered
in the taller row. Pin it to flex-start so it sits at top of the padding
box, exactly where the section back arrow sits.

…vent listener leak (#309906) (#310740)

…310868)

* Agents tunnels: auto-reconnect with backoff and wake-triggered retry

Tunnel-backed remote agent hosts previously had no auto-reconnect
behavior — on laptop sleep / network drop the tunnel would flip to
Disconnected and stay there until the user manually retried.

This adds a reconnect loop inside TunnelAgentHostContribution:

- Detect Connected→Disconnected transitions for still-cached tunnels
  and schedule an immediate reconnect. Only fires when the entry is
  explicitly Disconnected — if the entry has been removed (e.g. user
  clicked "Remove Remote"), we honour the removal and do not reconnect.
- Exponential backoff on consecutive failures: 1s → 30s cap, up to
  10 attempts, then pause.
- Wake-triggered retry: on browser `online` or tab
  `visibilitychange` → visible, resume any paused reconnects.
  Rate-limited to one resume per 10s so rapid tab toggling can't
  hammer a permanently broken endpoint with unbounded attempt bursts.
- Prune all reconnect state when a tunnel is uncached or the
  contribution is disposed.

…esults (#311065)

Co-authored-by: Copilot <copilot@github.com>

* feat: upload commit-to-version mapping for copilot source maps

During the Copilot CI build, after uploading source maps to CDN, also upload
a small JSON file at sourcemaps/{extensionId}/commits/{commitHash}.json that
maps the VS Code commit hash to the patched extension version.

This enables the vscode-errors deminify service to resolve the correct
extension version for Insider builds, where the version is date-patched
(e.g. 0.44.2026041004) and not derivable from the repo alone.

* fix: use no-cache for commit-version mapping blob

The mapping file could change on pipeline reruns, so use
no-cache instead of long-lived cache headers.

Only list Copilot SDK sessions that already have Agent Host session data, so sessions created by other Copilot CLI agents are filtered out without creating databases during listing.

(Written by Copilot)

…311095)

The CopilotAgent.getDescriptor() displayName was "Copilot" but should be
"Copilot CLI" to match the well-known CopilotCLISessionType label used
elsewhere. The remote agent host sessions provider uses this displayName
to build the session type label shown in the UI.
