fix(first-use): resolve current search before paste and clarify availability

[johnny4young]

Summary

Resolve keyboard paste against the current search/filter context, add welcome Back navigation, and clarify public download availability, direct-purchase price and neutral-text legibility.

Defect and behavior

Query invalidation retained previous rows while Enter and Command-V immediately consumed the selected item. The correction resolves current rows first, preserves Enter's exact-snippet priority and Command-V's selection behavior, and never falls back to old clips after empty results.

• Capture request identity synchronously, before scheduling asynchronous work
• Coalesce only identical interaction/plain/snippet intent; a changed intent replaces obsolete work
• Fence cleanup by request ownership
• Invalidate pending admission on newer input, selection/navigation, filter-rail movement, preview entry, dismissal and shortcuts-overlay opening
• Reject hidden keyboard paste while shortcuts are open and keep quick-paste/stack actions off stale rows
• Add Back after the first welcome step while retaining Skip and manual-paste fallback

Website copy explicitly says iOS/iPadOS is not yet available beside the macOS download. The direct-purchase $19.99 observation remains explicitly dated October 6, 2026; users review the final total and taxes on the existing Lemon Squeezy checkout. No purchase, currency inference or commerce change.
Neutral text tokens are adjusted with source-color checks across 28 theme/pair combinations. This is not complete rendered WCAG certification.

Duplicate and integration check

Freshly checked every open PR #193–201 against main. None implements this paste/onboarding/price/contrast correction. The original first-use candidate intersected #193 only at site/index.html and scripts/check-site.sh for its independent release chronology, imagery and preparation narrative. The latest test-only follow-up also reuses its already-existing PanelPrewarmedOpenUITests correction, as described below. Preserve that work during later integration. This PR does not include CI-cache experimentation, storage lease repairs, release metadata changes or a combined-stack qualification.

Verification

• Exact uploaded tree matches the reviewed local tree; branch update was forward-only with an expected-head check
• Site structural and product-truth checks pass
• Contrast suite: 4 tests covering 28 source-color pairs pass
• Four portable admission model/source-wiring controls pass; these do not execute Swift
• git diff --check passes
• make format, make lint and make test were attempted locally but are blocked by missing Swift/Xcode; no local native pass is claimed
• Native package tests include deterministic current-query, supersession, changed intent and cancellation coverage; the activation UI journey covers Back and first-step bounds
• Previous head 3080bf6 hosted CI 37653488965 passed: strict swift-format, SwiftLint (606 files, zero violations), 1,513 package tests in 232 suites, warning checks, 83.9% package production-source coverage above the unchanged 80% floor, StoreKit, and macOS/iOS app builds. Non-blocking beta canary skipped as expected
• Native current-query, empty-result, snippet/selection, changed-intent, supersession, early-input, peek, filter-rail and shortcuts cancellation regressions passed
• Initial failures are retained: strict formatter layout, test file exceeding the unchanged 700-code-line limit, and an old release contract still requiring the obsolete iOS label. Follow-ups only format source, move one self-contained test verbatim to a companion extension, and require the explicit unavailable label separately in both languages. No expectation, gate, coverage floor or release truth was weakened
• Full UI 37655673331 on 3080bf6 failed: iOS 21/21 passed; macOS 120 passed, one failed, three skipped. The sole failed test was PanelPrewarmedOpenUITests.testEveryOpenStartsOnTheNewestClipWithSearchFocused, the same inherited accessibility-query failure observed on main. This red result is retained and is not reclassified as a pass
• The current follow-up copies only Tests/GanchoUITests/PanelPrewarmedOpenUITests.swift verbatim from #193 at dc81042, blob 86805ebc3149e13d8c045f4090f9ebd2ce629f91. That existing correction asks for the element carrying the selected trait, rather than a same-label child. It retains initial newest selection, Down navigation, reopen selection and keyboard-focus assertions; no sleeps, suppressions or gate changes
• This is an explicitly shared test prerequisite already present in chore(release): prepare v0.10.0 #193, not a newly discovered independent fix. No other chore(release): prepare v0.10.0 #193 file, version bump, release narrative or merge is included. Main still lacks this correction; later integration should deduplicate the identical file
• Exact-head ordinary CI 37661608290 passed strict formatting, SwiftLint, package tests and the unchanged >=80% coverage gate, StoreKit tests, and both macOS/iOS app builds. The non-blocking beta canary was skipped as expected.
• Exact-head full UI 37679130425 passed: 121 macOS tests passed, three explicitly skipped; 21 iOS tests passed. The corrected prewarmed-open journey and modified activation journey are included. The three skips are not counted as passes.
• These results qualify head 377aa9f; no prior-head or other-PR run is substituted for exact-head evidence.

Limits

No merge, release, deployment, permission change, live clipboard inspection or installed-release mutation. Native installed-app paste delivery, accessibility/device behavior, rendered-browser qualification and the combined repair tree are separate from source checks. The scoped exact-head native gates are green; ready for review. This is not authorization to merge.
