Release 1.12.0 (build 26): search creates the note you typed, core 2.54.1

[adibhanna]

Release branch for ZenNotes iOS 1.12.0 (build 26). Build 26 is to be archived by hand from Xcode on 5d6d961 after this lands; nothing is submitted yet.

What changed since 1.11.0 (25)

• Core @zennotes/app-core 2.53.0 → 2.54.1 (2.54.1-core.h75d82a521571dc20, source ZenNotes/zennotes 0285443b = v2.54.1, clean tree; SHA-256 and integrity in vendor/zennotes/manifest.json). What the phone gets from it:
  • Note search creates the note you typed (desktop #826): the results end with a Create "…" row; it opens a New note form with the name filled in, a folder field (projects/ideas nests under Inbox), tags from the vault's list or typed new, and a same-name check that blocks Create in the chosen folder and offers to open the existing note instead.
  • The first tap on Create counts while a tag is still typed (2.54.1): the footer buttons no longer take focus on touch-down, so the Tags field is not blurred and the button does not move before the finger lifts.
  • Following a wikilink clears its target from the footer (desktop #820, reported from Android); leaving Reading mode opens the editor at the part you were reading (#822); the YAML header is plain text with Live Preview off (#827); a note whose text returns to what is on disk is not saved again (#828).
  • Not surfaced on the phone: Harper's dictionary fix (#829, the phones never run Harper), Vim half-page motions in visual mode (#825, hardware keyboard only), zn mcp flags (#831, desktop CLI).
• Shell fix for the new form: the palette is a full-screen takeover here and the shell's Cancel button sits where the form's header puts its destination label ("in Inbox"); the two overlapped. Two rules in src/ui-mobile/mobile.css end the header before Cancel begins.
• npm run core:adopt (tooling/adopt-core.mjs + adopt-core.test.mjs, the same files the Android shell has): downloads a core-* release, refuses it unless every SHA-256 and SHA-512 matches its provenance and all source commits agree on a clean tree, swaps vendor/zennotes/, rewrites the manifest, the file: pins and the README sentence, runs npm install and boundaries:check. README gains the "vendored set" sentence it needs.
• New SearchCreateUITests in AppUITests (2 tests): the form opens from search with the typed name, Create writes the note with its tag, and the header label clears the Cancel button (red on the old CSS, green after).

Deployment target stays iOS 15.0; no permission, entitlement, or SDK changes. Capacitor unchanged.

Verified on this tree

npm run boundaries:check (no override), npm run typecheck, npm test (124/124, 11 of them the adopt script's), npm run sync. Debug build with Xcode 27.0 (xcodebuild build … CODE_SIGNING_ALLOWED=NO) succeeds; App, ShareExtension and ZenWidgets all report 1.12.0 (26), MinimumOSVersion 15.0; the embedded public/index.html and CSS are byte-identical to dist/ and carry the data-search-create-form rules. Installed and launched on the iOS 27.0 iPhone 17 Pro Max simulator, restored the last note. SearchCreateUITests 2/2 pass on that simulator.

Merge as a fast-forward so main lands on the archived commit.
