nrobi144 4010a57e68 feat(desktop): add custom feeds system with creation, pinning, and inline switching

- FeedDefinition data model with FeedSource sealed interface (Filter, Following, Global, DVM, PeopleList, InterestSet, SingleRelay)
- FeedDefinitionRepository with StateFlow, groupedFeeds, pin/unpin/reorder (max 3 pinned)
- JSON serialization via Jackson with round-trip tests (18 unit tests)
- SearchQuery.toFeedDefinition() bridge for creating feeds from search
- FeedBuilderDialog with author search (cache lookup + npub decode), hashtag/relay inputs, kind filter checkboxes, exclude authors/keywords, Cmd+S save, Enter to add
- FeedsDrawerTab in app drawer with edit/delete/pin/unpin actions
- Feeds tab in top header (FilterChips) with inline mode switching
- CustomFeedScreen + DesktopCustomFeedFilter + createCustomFeedSubscription for relay-based custom feed content
- FeedDefinitionEvent (kind 31890) in quartz for future publish/import
- Local persistence via java.util.prefs.Preferences (auto-save on change)
- DeckColumnType.CustomFeed for navigation integration
- Renamed Home to Feeds in nav rail
- Fix: AnimatedGifImage race condition (coerceIn on frame index)
- Fix: search results margins (sidePadding applied consistently)
- Fix: app drawer search includes feeds in results

Feed Builder Enhancements

Date: 2026-05-05 Status: Implementation

Scope

Enhance FeedBuilderDialog with 6 items:

npub auto-decode (paste npub -> hex + display name)
Author search (type name -> search LocalCache -> pick)
Kind filter checkboxes (Notes, Reposts, Articles)
Edit + Delete feeds (CRUD completeness)
"Save as Feed" button in search results
Exclude authors field in dialog

Implementation

1. npub Auto-Decode

Where: FeedBuilderDialog.kt ChipInputField for Authors

Logic:

On add: if input starts with npub1, decode via decodePublicKeyAsHexOrNull()
If decode succeeds, add hex to authors list
Show display name in chip (resolve from LocalCache)

2. Author Search

Where: New AuthorSearchField composable in FeedBuilderDialog.kt

Flow:

Replace plain text field for authors with search field
Type >= 2 chars -> filter DesktopLocalCache.users by displayName/nip05
Show dropdown with matching profiles (avatar placeholder + name + npub short)
Click adds hex to authors list
Still allow raw npub/hex paste (falls through to auto-decode)

Data source: DesktopLocalCache.users (already populated from metadata subscriptions)

3. Kind Filter Checkboxes

Where: FeedBuilderDialog.kt, new section between relays and exclude

UI: FlowRow of FilterChips:

Notes (kind 1)
Reposts (kind 6, 16)
Articles (kind 30023)
Highlights (kind 9802)
Reactions (kind 7)

Default: Notes + Reposts checked. Maps to FeedBuilderState.kinds.

4. Edit + Delete in Drawer

Where: FeedsDrawerTab.kt

Edit: Add edit button on each FeedRow -> opens FeedBuilderDialog(initial = feed)

On save: calls feedRepository.update(feed)

Delete: Add delete in context or as swipe action

Confirm dialog: "Delete feed X?"
Calls feedRepository.delete(feed.id)

5. "Save as Feed" from Search

Where: SearchScreen.kt or SearchResultsList.kt

UI: Show "Save as Feed" button when query.canBecomeFeed() is true

Button appears in the header area, next to the search bar actions
Click opens FeedBuilderDialog pre-filled from query.toFeedDefinition()

6. Exclude Authors in Dialog

Where: FeedBuilderDialog.kt

UI: Same chip input pattern as regular authors but for excludes

Uses same author search/npub-decode logic
Maps to FeedBuilderState.excludeAuthors

File Changes

File	Change
`FeedBuilderDialog.kt`	Author search field, npub decode, kind checkboxes, exclude authors
`FeedsDrawerTab.kt`	Edit/delete buttons on feed rows
`SearchScreen.kt`	"Save as Feed" button
`FeedBuilderState.kt`	No changes needed (already has all fields)

Dependencies

decodePublicKeyAsHexOrNull from quartz/nip19Bech32
DesktopLocalCache.users for profile search
SearchQuery.canBecomeFeed() + toFeedDefinition() already exist
