* chore: bump electron@43.4.1
* linux: align desktop name and StartupWMClass
Give DEB and RPM installs a package owned reverse DNS desktop name
so runtime wayland portal identity resolves to an installed desktop file.
Keep snap and archive runtime identities aligned with their distribution
specific desktop file behavior.
Set StartupWMClass to the same identity used by the runtime.
* linux: respect native window controls layout
Reserve both left and right WCO safe areas so custom title bar content
does not overlap controls when the desktop environment places them on
either side.

Electron 43 defaults native dialogs without a defaultPath to the
Downloads directory instead of allowing the platform to retain its
last location. Resolve existing file or folder history before
invoking native open and save dialogs, while preserving an explicit
caller-provided URI.

registerHttpProtocol, and interceptFileProtocol APIs with protocol.handle().

Codex extension surfaced a renderer forced exit after hitting EMFILE on Linux
when a webview issued very large number of concurrent local resource fetches.
Diagnosis
- Codex extension can trigger roughly 625 concurrent webview resource requests.
- Webview resource loading currently forwards each request to the host and
begins transferring the returned body immediately.
- Disk reads are chunked at 256 KiB, and Mojo uses shared-memory FDs for
payloads above 64 KiB, so each in-flight resource body can consume file
descriptors in the renderer while it is being streamed.
- The sandboxed renderer runs with RLIMIT_NOFILE=1024 on Linux.
- This is not specific to codex extensionn, any extension with enough concurrent
resource bodies can accumulate to exhaust the renderer FD budget.
This makes the problem specifically about the number of simultaneously active
host-backed response bodies. A naive limiter around WebviewElement.loadResource()
would not address the root cause because loadResource() returns as soon as the
stream is transferred, while the FD pressure persists for the lifetime of the
stream in the renderer.
Introduce a service-worker-side global concurrency limit for host-backed webview
resource response bodies.
- Add a global limit of 32 active host-backed resource bodies in the webview
service worker.
- Acquire a permit before creating/posting the load-resource request so time
spent waiting for a slot does not consume the existing 30 second
RequestStore timeout.
- Hold the permit for the full lifetime of the returned ReadableStream, and
release it only when the stream reaches EOF, errors, or is cancelled.
- Release exactly once on all non-stream results and on every early/error path,
including timeout handling.
- Preserve existing range request behavior, ETag/304 handling, CacheStorage
behavior, Safari fallback streaming, and cancellation semantics.
- For cacheable responses, keep the permit until both source transfer and the
associated cache write complete, without delaying delivery of the response
back to the webview.
- Bump the service worker version and WebviewElement expected version together
so clients pick up the updated worker.
Tests
- Add an API integration regression test that creates a webview, materializes
many local resources, fetches them concurrently from inside the webview, and
verifies the webview stays alive and all loads complete.

* Default editor and panel chat to Agent Host Copilot when the agent host is enabled
Builds on the chat.editor.preferCopilotHarness behavior to make Agent Host
Copilot the computed default chat provider for both editor and panel chat
whenever the agent host is enabled, so first-time users land on Copilot instead
of Local. chat.editor.preferCopilotHarness stays scoped to the one-time
Local -> Copilot migration only.
- Thread an agentHostEnabled flag (from IAgentHostEnablementService) through the
default-session-type resolution and its callers.
- Keep Local visible and selectable; honor explicit and remembered selections.
- New Local Chat opens a local session directly: it cancels the in-flight
default-provider resolution (which would otherwise block on agent host
activation) so the local request wins immediately.
- Open a Local chat first in all chat participant API tests, since chat
participants are a Local-harness feature.
- Add a smoketest.openLocalChat command for Local panel smoke scenarios; the
sandbox reopen path reveals the existing local session to avoid a focus race.
- Register an IAgentHostEnablementService stub in the component fixtures.

* chat: honor resolved session type when starting a new chat
Fixes the New Chat drop bug (review comment #2 on #326086): when the
agent host is enabled the computed default is a non-local harness, so the
editor clear path recomputed that default and dropped explicit or
preserved local requests.
- clearChatSessionPreservingType now branches on the resolved session
type for the sidebar (non-local -> loadSession, local ->
startNewLocalSession) so a generic New Chat from a Local panel
preserves Local, consistent with contributed panels.
- The resolved type is threaded through IChatWidget.clear ->
viewOptions.clear -> chatEditor.clear -> clearChatEditor so the editor
opens a session of that type instead of recomputing the default. This
restores explicit "New Local Chat" from a non-local editor.
- clearChatEditor applies an explicit target type directly and keeps its
swap-aware default only for direct (untargeted) calls.

* chat: cancel the previous applyModel resolution before replacing it
Assigning a new CancellationTokenSource to the MutableDisposable only
disposes the previous source, and disposing a CancellationTokenSource
does not cancel it. So a re-entrant applyModel() (view render, switch
session) left the prior in-flight resolution running, racing to call
showModel with a stale result. Cancel the previous source explicitly
before replacing it.

vscode-api-tests: use explicit "types" instead of "typeRoots"
Switches tsconfig from typeRoots-only (which only auto-includes @types/* found at the literal path ./node_modules/@types) to an explicit "types" list. Explicit types resolve via Node module resolution, so they keep working regardless of whether npm hoists @types/node to the workspace root or keeps it extension-local.
Refs microsoft/vscode-engineering#2912 — the recurring TS2591 "Cannot find name 'process'" failure on the build agent after #319389 changed the lockfile is consistent with @types/node being hoisted to a path the typeRoots-only config can't see. Matches the pattern already used by extensions/github, extensions/copilot, etc.
