feat(swift-ios): add pull-down command drawer

[saphid]

Summary

• Adds the complete native SwiftUI command drawer: visible Home/thread entry, searchable action/thread/project catalog, selection, and dismissal.
• Adds the pull/open/close gesture lifecycle while leaving ordinary list and transcript scrolling alone.
• Restores the exact prior responder after an abandoned pull or gesture close, so keyboard input resumes without another tap.

SwiftUI-only. This is the consolidated implementation for #86, #122, #135, and #154 and supersedes the former stacked draft #8350.

Proof

Exact target b67837984e5650888b1eed0e1cd7fff83625f696 → head c1eef5a073bf25dfb277882444f187c1f64647b9.

The dark-mode sequence shows prior, an abandoned pull followed by restored, then a complete pull/open/gesture-close followed by returned. Both suffixes were typed without tapping Home search; the caret and software keyboard remain with the same field.

Exact-target and light-mode context

Exact-target pull — the same top-edge pull leaves Home unchanged because the live target has no drawer.

Test

• FeatureCommandDrawerTests + FeatureCommandDrawerPresentationTests: 61 passed, 0 failed on iPhone 16 Pro / iOS 26.5.
• Timeline-derived current-head and exact-target media packets: passed.
• Current-head semantic snapshots are bound to the protected command-drawer lane.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This is a substantial new iOS capability that adds a searchable command drawer, global pan-gesture arbitration, keyboard/focus handoff, and routing from both Home and thread detail. Because it changes core workspace interaction and introduces cross-view UIKit/SwiftUI lifecycle behavior across several production files, it warrants human review.

Adds the command drawer's gesture and fixes how it presents. The drawer now opens on a plain downward swipe that starts anywhere on the app's top bar — Home, an open thread, and the other pushed surfaces alike — instead of only on a deliberate long drag: the settle is an absolute commit distance measured from the rest position the drag started at, with the release's momentum projected a little ahead, so a short fast swipe commits on speed and a slow one on position, and the push that closes the drawer is as short as the swipe that opened it. Eligibility is unchanged, so Home's thread list and the thread transcript keep every ordinary scroll and the status bar above the safe-area inset stays the system's own notification-shade gesture. The drawer is also presented over the workspace rather than pushing it: the page underneath no longer translates at all, so the rows, header and composer stay exactly where they were while the drawer and its scrim move with the finger (measured on the simulator as a 0-pixel shift of the background, with a sharp minimum). Finally, the search field now reliably takes focus — the request is made when the pull starts, which is what puts the keyboard's height into the drawer's open height before the finger lifts, but at that moment the field is still above the window's top edge and the request can be dropped; it is now renewed once the drawer is open and still unfocused, so the keyboard arrives on every entry path including a quarter-second swipe. FeatureCommandDrawerTests covers the settle thresholds, the grab band against both top bars in the app, the drawer's offset against the open edge it advertises, and the focus-renewal contract: 38 tests, all passing on this head.

Desperately needs screenshots and videos

[saphid]

Added the visual proof to the PR description:

• screenshots of the drawer open over Home and over an active thread, both with the keyboard visible
• a 42.5s video covering the drawer gesture and presentation from both surfaces
• a 51.7s video showing Home list scrolling remains independent of the drawer gesture

The assets are committed in 8f3b994a2.

nope those are old

[saphid]

Replaced the obsolete command-palette media with fresh captures from the current SwiftUI PR build.

• Light mode: pull open the new flat command drawer, filter to Settings, and route to Settings (16s)
• Dark mode: pull open the new flat command drawer, filter to New task, and route to the composer (15s)
• Added matching light/dark screenshots
• Removed all four stale screenshots/videos from the previous upload

The PR description now embeds/links the replacements from commit 0e4ee4391. I reviewed sampled frames across both clips and verified the files served by GitHub match the local captures byte-for-byte and decode cleanly.

[saphid]

Updated the visual proof again with a populated simulator environment: 3 projects (T3 Code, React, Linux) and 9 recent threads.

The replacement videos now open on the populated Home list and show the unfiltered drawer before searching:

• light: browse the thread/project catalog, search react, select the React project, and land on filtered Home
• dark: browse and scroll the catalog, search boot, select the Linux thread, and open that conversation

The two replacement screenshots also visibly include the recent thread rows and all three project actions. Assets are in 9f3a8706d; I reviewed the final encoded contact sheets and verified the GitHub-served files byte-for-byte.

[saphid]

Re-recorded both videos with the iOS software keyboard explicitly visible for the complete drawer search interaction.

• the drawer opens with the keyboard already raised
• react and boot are entered through individual taps on the visible simulator keyboard, not hidden text injection
• the populated thread/project results remain visible above the keyboard
• the matching light/dark screenshots now include the keyboard too

Replacements are in b3a467304. I reviewed the final encoded frame sheets for keyboard presence and verified the GitHub-served MP4s byte-for-byte with clean full decodes.
