feat(web): sticky provider options and Grok composer affordances

[EnzoTironi]

What Changed

• Sticky composer options fall back when the per-thread draft has no options, so picker changes (e.g. Grok effort) reach sendTurn on existing threads
• Sticky does not override the thread/project model slug
• Sticky options re-keyed under the selected instance id (custom instances work)
• Gate built-in /plan /default slash items on showInteractionModeToggle
• Remove Grok "Early Access" badge

Fixes #5421

Why

Without sticky option fallback, changing effort on an existing thread kept stale thread-turn options. Folding sticky into selectedModel would silently switch models — fixed so sticky is options-only.

UI Changes

Grok Early Access badge removed

Before (badge present):

After (badge removed; Cursor still has Early Access):

Composer effort control (sticky options apply to this picker)

Sticky is send-payload behavior (no new components). /plan slash only when the provider exposes plan mode.

Checklist

• This PR is small and focused (~+237 / 4 files)
• I explained what changed and why
• Before/after screenshots for badge removal
• Effort picker screenshot (sticky option surface)
• Video N/A

Test plan

• composerDraftStore unit tests (sticky options, model preserve, instance re-key)

Model: grok-4.5 (Grok Build)

Note

Medium Risk
Changes send-time model option resolution across threads and custom provider instances; wrong precedence could ship stale or cross-provider options, though behavior is heavily unit-tested.

Overview
Sticky composer options now feed deriveEffectiveComposerModelState when the per-thread draft has no options for the selected instance, so picker changes (e.g. Grok reasoning effort) apply on existing threads without overriding the thread/project model slug. Resolution is instance-scoped: options from other instances or kind-keyed legacy drafts no longer block sticky, and sticky options are re-keyed under the active custom instance id.

Grok is included in setProviderModelOptions draft persistence, the Grok Early Access badge is removed in settings metadata, and built-in /plan / /default slash menu items only appear when showInteractionModeToggle is true (hiding no-ops on providers like OpenCode).

Unit tests cover sticky vs draft/thread precedence and Grok sticky persistence.

Note

Add sticky provider options and Grok composer affordances in the chat composer

• deriveEffectiveComposerModelState now accepts stickyModelSelectionByProvider and uses it as a fallback when the draft lacks options for the selected provider instance, without affecting model slug resolution.
• Option lookups are scoped to the selected provider instance via a new optionsForInstance helper, replacing the broader modelSelectionByProviderToOptions.
• Grok is added to the providers whose options are persisted in setProviderModelOptions, matching the behavior of codex, claudeAgent, cursor, and opencode.
• /plan and /default slash commands are gated behind composerProviderControls.showInteractionModeToggle, hiding them for providers that don't expose an interaction mode toggle.
• The "Early Access" badge is removed from the Grok provider entry in providerDriverMeta.ts.

Approvability

Verdict: Needs human review

This PR introduces a new feature (sticky provider options) that changes how model options persist across threads, adding new user-facing capability. New features introducing runtime behavior changes warrant human review.

Review findings from Bugbot/Macroscope for this slice are fixed on the Zoen product tip (zoen/main @ 16474ab0d). Will restack / re-push these PR heads after further slim-slicing. Open remaining: effort restart without session.exited (or adopt #5403 set_model path).
