feat(web): pick settings environment and project as two selects

[juliusmarminge]

The Projects page had separate machine/project controls and could not name one physical checkout when the same repository appeared more than once on an environment. The first cut replaced them with a single searchable combobox mixing environments, projects and checkouts in one list, which was hard to use without searching.

This adds the scope model (settingsScope.ts: resolve a URL target to an environment, project, or exact checkout, with stale targets resolving to an explicit unavailable state rather than widening a write) and two independent selects: an environment select and a project select. A project is the same project on every environment, so the project list is flat and the environment select alone decides where a change is written. A legacy ?project&checkout link still resolves to its one environment, and the environment select reflects that instead of reading All environments. Existing project operations receive the selected members.

Depends on #11176; followed by #10639, which moves the selects into the Settings breadcrumb for every category.

Verification: focused scope-resolution, axis-mapping and project-selection tests, web typecheck, changed-file lint.

Evidence

Head 013f32b6d4, rebased onto codex/hierarchical-settings/backend. On this layer alone the selects render at the top of the Projects page; the integrated stack moves them into the breadcrumb, see #10639.

Model: Claude Fable 5.1 (picker rework) and GPT-5 (scope model). Harness: Claude Code and Codex.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a new two-axis settings scope workflow and resolver while changing existing project filtering and navigation behavior. The production runtime impact is broader than a mechanical UI cleanup or bounded opt-in change, so human review is warranted.

No code changes detected at 013f32b. Prior analysis still applies.

📝 Walkthrough

Walkthrough

Settings now use a unified scope model for environments, devices, projects, checkouts, aggregate targets, and unavailable targets. Routing, scope selection, project rendering, and checkout-specific navigation use the shared model.

Changes

Settings scope selection

Layer / File(s)	Summary
Scope contracts and resolution apps/web/src/components/settings/settingsScope.ts, apps/web/src/components/settings/settingsScope.test.ts	Adds scope types, validation, resolution, and tests for aggregate, device, environment, project, checkout, stale, and unavailable targets.
Scope groups and picker apps/web/src/components/settings/useSettingsProjectGroups.ts, apps/web/src/components/settings/SettingsScopePicker.logic.ts, apps/web/src/components/settings/SettingsScopePicker.logic.test.ts, apps/web/src/components/settings/SettingsScopePicker.tsx	Adds memoized project groups, shared environment labels, checkout-aware selection, disambiguated labels, tooltips, and wrapped option text.
Route and settings rendering apps/web/src/routes/settings.projects.tsx, apps/web/src/components/settings/ProjectsSettings.tsx	Passes unified scope values through the route and renders project, default, device, or unavailable states.
Checkout-specific project details apps/web/src/components/settings/ProjectSettingsPanel.tsx	Filters members by checkout, preserves checkout navigation, handles unavailable checkouts, remounts details when the checkout changes, and updates grouped-project removal navigation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to d8f75

Checkout-specific settings remain scoped to the removed checkout after deletion, preventing later edits from applying to sibling checkouts. No current merge-blocking risk remains.

861-861: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Retain the active scope after checkout removal.

When a checkout-scoped panel removes its selected checkout while other members remain, Line 861 redirects with only project and clears machine. It also drops checkout. The next page becomes an unscoped project view, so later edits can apply to remaining checkouts instead of showing the selected checkout as unavailable. Preserve the active machine and checkout values for this redirect.

Fixed the outside-diff checkout-removal finding in d8f7547. Removing a selected checkout now leaves its exact project/environment/checkout URL unchanged instead of selecting its surviving siblings. The isolated browser test confirmed an unavailable selection with no editable project controls; 19 scope-resolution tests pass, including checkout and last-local-member deletion cases. Evidence is in the PR body.
