`whenWorkbenchRestored()` can be answered by the pre-reload document, so the
'Extension Host Restart' tests continued while the window was still reloading.
The next test then dispatched its command palette keybinding into a tearing
down window, `openQuickAccessWithRetry` exhausted its retries and fell through
to `type()`, which failed with a misleading 'set value ... after 20 seconds'.
Add `Code#reloadWindow()` which stamps the current document, triggers the
reload and waits for a new document before awaiting the workbench restore.
The suite drives the browser toolbar overflow and Add to Chat menus through HTML locators (.monaco-menu-container). On macOS, stable defaults window.menuStyle to 'native' while insiders defaults to 'inherit', so those menus render as native OS menus in stable and the locators never resolve.
Pin the setting to 'custom' for the suite, seeded on disk before startup. Writing it at runtime instead would make SettingsChangeRelauncher pop a modal 'restart to take effect' dialog on Windows/Linux, blocking the workbench.
Ports #328969 and #328972 from release/1.132 to main.

Switching Add Context to `Codicon.addCompact` changes the `+` in the
inline chat zone widget, which is a blocks-ci fixture.
Verified the change is intentional and confined before accepting the new
hashes: rendering the fixture on this branch and on its merge-base and
diffing them locally shows a single 12×12px region differing — the `+`
glyph going from 11×11 to 10×10 of ink. That is the optically tuned
compact glyph replacing the scaled-down base one, at a call site already
rendering at `codiconFontSize-compact`, which is the pairing the design
tokens guidance asks for. Nothing else in the widget moved.
Hashes are exactly the ones the failing run computed.

* telemetry: report ResizeObserver delivery context
The browser's ResizeObserver loop ErrorEvent contains only a generic message; it does not expose the skipped target or causative callback. Prefixing that warning with the most recently invoked DisposableResizeObserver therefore turned callback order into false causal attribution.
Record the wrapped observers that ran in the current rendering frame instead. Context is scoped per window, deduplicated, sorted for stable bucketing, and bounded to the canonical smallest eight names plus an overflow marker. The telemetry prefix explicitly calls these recent wrapped observers rather than an offending consumer.
Clear context at the next animation frame, after Blink dispatches any loop warning from the current rendering update. Unit coverage locks deduplication, canonical overflow, window isolation, and frame cleanup; a real Chromium component fixture deliberately triggers a self-resize loop and verifies context survives until the native warning.

* telemetry: shorten ResizeObserver context prefix

Chat telemetry reported a large volume of "ResizeObserver loop completed
with undelivered notifications" warnings attributed to
ChatInputPart.containerHeight. That attribution is misleading: the loop
error is dispatched by Chromium after the observation phase, so the
DisposableResizeObserver name recorded is simply whichever observer
fired last, not the one that caused the loop.
The actual cause is in ChatListItemRenderer. Row templates observed
their rowContainer for the entire template lifetime, but the chat list
is virtualized and recycles rows. When an observation phase disconnects
an observed target, its notification can never be delivered, and the
browser raises the loop error.
Bind the row observation to mount state using the existing
connection-observer element: observe on connect, clear on disconnect.
This is synchronous with mount, so it needs no frame deferral.
Also stop ChatViewPane's stacked-sessions input-height autorun from
re-entering inputPart.layout(). It now uses a targeted path that
updates the height budget and lays out only list-side surfaces.
Adds a component-explorer harness with fully mocked model traffic and a
Playwright regression covering four host-layout scenarios, plus a unit
test locking the targeted layout dispatch order.

* 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.
