Feedback #30: Ability to copy/paste images from clipboard into Feedback and Briefs and Inbox inputs to have those images auto-attach to the messages

Merged flower/138-clipboard-image-paste → master as merge commit 277fb73. Post-merge on MAIN: migration create_attachments_table applied; full suite green (749 tests, 747 passed, 2 skipped, 5007 assertions); pint clean. Shipped: polymorphic attachments table + Attachment model (filesystem storage via config flower.attachments.disk, no base64), streamed GET /attachments/{id} route (no storage:link needed), HandlesImageAttachments concern + x-ui.image-attach / x-ui.attachment-thumbs + Alpine @paste wiring across /feedback, both /briefs composers, and Inbox; 8 new tests. No Horizon reload (UI, not job code). ⚠️ CAVEAT (worker-flagged): server-side flow is fully unit-tested but the pure-JS clipboard paste handler can't run in phpunit — worth a quick manual browser paste check on flower.test. Merged by flower-orchestrator (daemon 16).

BUILT on flower/138-clipboard-image-paste (commit f8d7d24). Clipboard-image paste + attach across all 3 operator composers — /feedback "Report a bug/idea/note", /briefs capture + brief add-note, and Inbox note. Design: - New polymorphic `attachments` table + Attachment model. Files stored on the filesystem disk (config `flower.attachments.disk`, default `public`) — pointer+metadata only, never base64. Row-delete removes the underlying file. - `App\Livewire\Concerns\HandlesImageAttachments` (WithFileUploads): `incomingImages` (paste/file-pick landing) drains into `stagedImages` (persists across requests) so multiple pastes accumulate; validates image/mimes/size/max-count; `persistImageAttachmentsTo(record, actor)` stores + attaches then clears. - Reusable Blade: `<x-ui.image-attach>` (Attach-images button + hidden file input + staged thumbnail previews with remove) and `<x-ui.attachment-thumbs>` (saved display). Paste is a no-build global `window.flowerImagePaste($event,$wire)` in the layout, wired via `@paste` on each composer <form>, handing clipboard blobs to Livewire uploadMultiple. - Attach targets: Feedback→Feedback record (rows + detail card); both brief composers→their NoteAdded BriefEvent (inline in the trace timeline); Inbox→OperatorNote (under the note). Serve via `GET /attachments/{attachment}` (streamed) so images resolve with or without storage:link. Gate: `~/bin/php artisan test` green (747 passed, 2 skipped). New tests/Feature/Attachments/ComposerImageAttachmentsTest.php (8 cases: all 3 composers + accumulate/remove + non-image reject + route-serve + file cleanup). pint clean on touched files. Bumped briefs/{brief} query budget 19→20 for the one bounded trace-attachments eager-load. Note: server-side flow (staging→persist→display→route) is fully unit-tested; the pure-JS clipboard `paste` handler can't run in phpunit — recommend a quick browser paste check on MAIN after merge. No merge/push/daemons per contract.

Feedback #30 Authority: OPERATOR APPROVAL REQUIRED Funnel: A - operator approved brief Gate: this brief must not be dispatchable until the operator approves it. Kind: idea Source: operator:ui Summary: Ability to copy/paste images from clipboard into Feedback and Briefs and Inbox inputs to have those images auto-attach to the messages Detail: Most of the time I'm doing this with images copied to my clipboard - which I assume are base64 encoded strings when I paste them somewhere? Can we either auto-handle that or just have an 'attach images' button/feature that I can click to open something that will accept my pasted images? Generally these are screenshots I want to include for context/visual.
