Pull Request: Save Queue as Playlist & Queue Edit Improvements

Summary

Adds the ability to save the current playback queue as a new private playlist, plus several queue edit-mode fixes and UI polish: per-row removal for duplicate songs, a remove-duplicates action, icon-only footer controls with tooltips, and a layout fix for misaligned queue rows with long titles.

Type of Change

• New feature (non-breaking change that adds functionality)
• Bug fix (non-breaking change that fixes an issue)
• UI/UX improvement

Features

Save Queue to Playlist

• New Save to Playlist action in the queue edit panel footer (icon: text.badge.plus)
• Opens an NSAlert sheet to name the playlist
• Creates a private playlist via existing playlist/create API, seeding all queue videoIds in order
• Updates library caches and notifies LibraryMutationBroadcaster (same pattern as song context menu “Create Playlist…”)
• Accessibility ID: queueView.saveToPlaylistButton

Remove Duplicates

• New header button in queue edit mode (icon: arrow.triangle.merge)
• Tooltip: Remove Duplicates: delete repeated songs from the queue and keep the first occurrence of each.
• Enabled only when queueHasDuplicateEntries is true; faded when inactive but still hoverable for the tooltip
• Keeps the first occurrence of each videoId; realigns currentIndex if the playing entry was a later duplicate
• Accessibility ID: queueView.removeDuplicatesButton

Queue Footer UI (Edit Mode)

• Footer actions are icon-only with hover tooltips (Undo, Redo, Shuffle, Save to Playlist, Clear)
• Layout: Undo + Redo grouped on the left; Shuffle, Save, and Clear distributed across remaining width
• Clear remains red; disabled states use reduced opacity

Bug Fixes

Remove only the selected queue row (duplicates)

Problem: Deleting one instance of a duplicated song could remove every copy in the queue.

Fix:

• Added removeFromQueue(at:) — removes by index, not videoId or shared entry ID
• Side panel and popup queue UI now pass row index for context menu, swipe, and remove actions
• removeFromQueue(entryIDs:) removes by index (highest first) for batch safety

Misaligned queue rows (long titles)

Problem: Rows with long titles (e.g. featured artist lists) could shift left, overlapping the index number and thumbnail.

Fix:

• Replaced horizontal NSStackView cell layout with pinned Auto Layout (fixed leading index + thumbnail, fixed trailing duration/like/badge, truncating middle text)
• Enabled table cell reuse via makeView(withIdentifier:)
• Normalize row view frames after swipe-to-remove feedback and drag operations
• clipsToBounds on cell to prevent visual bleed

Testing

Automated

swift test --filter PlayerServiceQueueTests

New/updated tests:

• removeFromQueueAtIndexRemovesSingleDuplicate
• removeDuplicateQueueEntriesKeepsFirstOccurrence
• queueHasDuplicateEntries

Manual

• Build queue with 5+ songs; Save to Playlist → name → verify playlist in Library
• Add same song 2–3 times; remove one row → only that position removed
• With duplicates present, click Remove Duplicates → only first occurrences kept
• Hover footer/header icons → tooltips appear (including when disabled)
• Scroll queue with long titles → thumbnails and index numbers stay aligned
• Partial swipe-to-remove then cancel → rows stay aligned

Build

swift build
KASET_SIGNING=adhoc ./Scripts/build-app.sh debug

Install to /Applications (use ditto, not cp -r, because of Sparkle symlinks):

ditto .build/app/Kaset.app /Applications/Kaset.app

Checklist

• Uses existing playlist/create API (no guessed endpoints)
• No secrets/cookies in code or docs
• Unit tests added for queue duplicate behavior
• Accessibility identifiers for new buttons
• swiftlint --strict && swiftformat . run before submit
• Full swift test --skip KasetUITests run before submit

Suggested PR Title

Save queue as playlist and improve queue edit mode (dedupe, alignment, icon footer)

Prompt Request (for reviewers)

Add a "Save to Playlist" button in queue edit mode that saves the full queue via playlist/create. Fix queue removal so deleting one duplicate only removes that row. Add a header "Remove Duplicates" control. Make footer actions icon-only with tooltips and fix misaligned rows for long song titles in the AppKit queue table.
