Add SwiftUI feedback package and Codex tagging skill

[StoneHub]

Adds a macOS SwiftUI companion to Dev Feedback Capture: pick tagged controls, save local change requests, and export selected notes with stable IDs and source locations. Activation uses a development-only Developer menu and Cmd+Option+Shift+F; the idle window has no injected controls or reserved space. The package provides a separate feedback panel, drafts preserved across navigation, local History editing, explicit Markdown/JSON exports, and Finder access. Release builds compile capture out.

Nested registrations preserve children. For example, a tagged transcript card can also expose its mode label, timestamp, text body, and actions; picking uses the smallest registered bounds under the click. The integration skill requires checking those independently discussable parts, static labels, and non-sensitive repeated-instance keys. A real SwiftUI hosting regression reproduces the old parent-overwrites-children failure and passes with the fix.

Jot (formerly Porch Speech) is the first host integration. Original capture/save/export/persistence installed proof is recorded in host PR #3; the latest host task is incorporating granular History tags and package snapshot 0107bd1. This is a local/vendored prototype, not a standalone Swift package release or published plugin. Agents read its native JSON through file tools; the browser MCP importer does not yet accept this schema.

Validation: eight Debug tests pass, including actual nested-view rendering; a Release test proves that target metadata expressions are not evaluated. Public Release modifiers are inlinable no-ops with lazy arguments; feedback UI/store implementation and menu entries are compiled out. All 49 browser/Electron/MCP tests and release checks pass. Browser ZIP verification passed for the initial package addition; browser files remain unchanged. Plugin and skill validation pass. Jot installed proof confirms separate mode/speaker label, copy icon, and parent whitespace picks with opaque instance keys and no transcript payload. The final menu-based build is signed and installed; its Developer menu is present and persistent Feedback UI is absent. The shortcut was subsequently verified live. An observed scroll bug is fixed by explicit feedbackViewport boundaries: clipped bounds drive both outlines and hit-testing, with hidden targets omitted. Tests cover partial and hidden rows plus real nested viewport propagation. Installed post-scroll visual proof is pending an unlocked Mac. The signed Release artifact passed host checks for DEBUG and forbidden feedback runtime/metadata markers. Current package GitHub checks are green.
