feat(web): Discord-style search operators in the command palette

[devin-ai-integration]

What Changed

Adds Discord-style search operators to the root command palette (web). Only apps/web is touched; the inline sidebar search and project-scope combobox on main are left as-is.

• in:<project> (quoted names supported, in: autocompletes projects under Filter by project; Enter commits in:Name (quoted only if the name has spaces) and keeps the palette open)
• provider:<provider> (provider: autocompletes providers under Filter by provider, with provider icons)
• Typing a bare word that prefixes an operator (a, be) appends a Search filters group after the results listing the matching operators with a one-line description; picking one rewrites the word to keyword:. It trails the results so Enter still selects the first real result.
• before: / after: / on: with ISO days, 7d/2w, today, yesterday. Unparseable dates fall back to plain text.
• Operator tokens are stripped before the query is sent to useThreadSearch, so only residual text hits the server content search.
• Archived threads are included in root-search results (loaded via useArchivedThreadSnapshots only while a non-empty root query is active; live shells win over archived duplicates). Selecting one restores it, waits for the restored shell to land in the store (waitForThreadShell, modelled on waitForProject), then opens it.
• Committed operators (token followed by a space) become real chips rendered inline between the search icon and the input, like a tokenized input (Discord, Gmail). CommandInput gains a leading slot for this; when it is set, the icon moves into a fixed-width zone with the same left edge so it does not shift. The palette keeps one canonical query string (tokenizeThreadSearchQuery / composeThreadSearchQuery), so parsing, filtering and the in: autocomplete are unchanged. Chips have an x button; Backspace with the caret at position 0 removes the last chip. Chips read keyword: [icon] value: in: shows the project favicon on an exact name match, provider: shows the provider icon. Chips/autocomplete are suppressed in > actions-only mode and in submenus.

Files: threadSearchQuery.logic.ts (+tests, pure parser and tokenizer), CommandPalette.tsx, CommandPalette.logic.ts (+test update), ui/command.tsx, state/entities.ts.

Why

Users with many projects and providers can only filter palette results by free text today; there is no way to scope by project, provider or date, and archived threads are unreachable from the palette. This ports the palette half of an older map-sidebar-project-search branch onto current main without reintroducing the stale sidebar rewrite.

Reproduction (before)

Setup: vp run dev --home-dir .t3/search-test on origin/main (7a368fe7c), two projects (Atlas, Beacon), fixture threads across Codex/Claude and dates, one archived Atlas thread.

Steps: Ctrl+K, type in:Atlas; then after:7d.
Expected: threads scoped to Atlas / updated in the last 7 days.
Actual: "No results" and the text is treated as a literal title search; archived thread never appears.

UI Changes

Before (main): in:Atlas	Before (main): after:7d

Note: screenshots and recordings below predate the agent: → provider: rename (ecedf1782); only the operator keyword/label changed.

After: combined in:Atlas agent:Codex after:7d (light)	After: same query (dark)

Chip close-up (light)	in: completion close-up

agent: autocomplete	Operator hints for a bare a

Autocomplete flow (in: pick, agent:co pick, a hints, click after:):

Chip interaction (pick in: suggestion, commit agent:/after: by typing a space, Backspace pops a chip, x removes one):

After: in: autocomplete	After: on:today	After: invalid date stays literal

> actions mode: no chip	Long in: value truncates	Archived hit, first click opens the real thread

Archived-hit interaction (re-archive, search yesterday, click, thread opens on first selection):

Verification

• vp test run apps/web/src/components/threadSearchQuery.logic.test.ts apps/web/src/components/CommandPalette.logic.test.ts: 69 passed
• vp run --filter @t3tools/web typecheck: clean
• vp lint on changed files: only 3 pre-existing react(set-state-in-effect) warnings in untouched open-intent effects
• vp run knip:check: clean
• Browser pass (Chrome, isolated .t3/search-test state) covering every operator, autocomplete, actions-only, submenus, and the archived first-selection flow on 45915804c. The inline chips were re-verified on the latest commit in light and dark: chip creation from the suggestion and from a typed space, Backspace and x removal keep focus, before:banana and in: stay text, > in:Atlas stays in actions mode, and the search icon does not move between the no-chip and chip layouts (0px at 1600px viewport). The provider: autocomplete, operator hints, and the keyword: icon value chip order were verified on 41bf3b1e0 along with the same regressions.

Verification blockers: none for the palette. Provider execution was not exercised (no Codex/Claude CLI auth on the test box); the feature is provider-independent.
