chore(release): 0.1.1

Bump version to 0.1.1 (package.json, Cargo.toml, Cargo.lock), date the
changelog section (2026-06-23), and add the GitHub release-notes draft.

QoL release on top of 0.1.0: custom multi-folder picker, theme system,
timeline scrubber, folder reordering, gallery/duplicate-finder
virtualisation, video playback settings, rebuild-semantic-index action,
plus AVIF thumbnail, video-embedding, and Subtle Light theme fixes.

 ### Added
 
+- **Custom multi-folder picker** — replaces the native OS dialog with an
+  in-app folder browser that lets you navigate, stage folders from multiple
+  locations, and add them all in one go. Duplicate roots are skipped
+  automatically; partially-failed batches remove successfully-added entries
+  from the staging panel so only failed folders remain to retry.
+- **Rebuild semantic index** maintenance action in Settings — drops and
+  recreates the vector tables at the current model dimension, then re-queues
+  every image for embedding. Fixes "dimension mismatch" search errors that
+  occur after switching between CLIP models with different output sizes.
+- **Video playback settings** — new Video Playback group in Settings with two
+  persisted toggles: "Autoplay in lightbox" (default on) and "Start muted"
+  (default off). Settings apply to the next opened video rather than the
+  current one.
 - **Timeline scrubber** — a year/month rail on the Timeline view that jumps to
   any period in the library. Timeline now loads the full filtered set so the
   scrubber spans the whole library instead of just the first page.

 ### Changed
 
+- Settings sections are reordered — General is now the first and default
+  section instead of AI Workspace.
+- The Duplicate Finder group list is now virtualised — only on-screen cards
+  mount, so large result sets (e.g. 5,000+ pairs) scroll without lag rather
+  than mounting every thumbnail at once.
 - The gallery grid is now row-virtualised, so very large libraries scroll
   smoothly and only on-screen thumbnails are rendered.

 ### Fixed
 
+- **AVIF thumbnails** — AVIF files are now processed correctly by routing
+  thumbnail generation through the bundled FFmpeg path instead of the Rust
+  image decoder (which has no dav1d dependency). Previously-failed AVIF jobs
+  are requeued on startup; JPEG derivatives are fed to the embedding and
+  tagging pipeline while the lightbox continues to display the original file.
+- Accent text is now readable in the Subtle Light theme.
+- Folder picker chevron tooltip now correctly shows "No subfolders" for leaf
+  entries instead of "Open folder" in both branches.
+- Folder picker Unix breadcrumb root now shows "/" instead of always "Home"
+  for non-home paths such as `/mnt/data`.
 - Video embedding jobs are no longer claimed before their thumbnail exists, and
   any that previously failed for that reason are requeued on startup — videos no
   longer churn through failed embeddings.

+# Phokus v0.1.1
+
+> Draft for the GitHub Release body. Fill in the checksums and trim as needed.
+
+**Phokus is a local-first desktop media library for Windows** — point it at
+your image and video folders and it builds a fast, searchable gallery with
+thumbnails, semantic search, visual discovery, AI tagging, and duplicate
+cleanup. Everything is processed on your machine; nothing is uploaded.
+
+This is a quality-of-life release on top of 0.1.0: a new in-app folder
+picker, themes, smoother scrolling on large libraries, and a batch of fixes.
+If you're updating from 0.1.0, the built-in updater will fetch this for you.
+
+## Install / update
+
+- **Updating from 0.1.0:** the in-app updater will offer 0.1.1 on launch — one
+  click downloads, installs, and relaunches.
+- **Fresh install:** download `Phokus_0.1.1_x64-setup.exe` below and run it.
+  **Windows SmartScreen will warn** that the publisher is unrecognized — this
+  build is **not code-signed**. Click **More info → Run anyway**.
+- Requires **Windows 10/11**. WebView2 is fetched automatically if missing.
+
+NVIDIA users wanting GPU embedding speed can use the
+`Phokus_0.1.1_x64-cuda-setup.exe` variant instead (larger download; bundles the
+CUDA runtime DLLs).
+
+## Highlights
+
+### Added
+- **Custom multi-folder picker** — navigate and stage folders from multiple
+  locations and add them in one go, replacing the native OS dialog.
+- **Themes** — Phokus, Subtle Light, and Conventional Dark chrome, with an
+  inline theme picker in first-run onboarding.
+- **Timeline scrubber** — a year/month rail to jump anywhere in the library.
+- **Folder reordering** in the sidebar (drag-and-drop or keyboard), persisted,
+  plus A–Z / Z–A / Custom sort for the Libraries list.
+- **Video playback settings** — autoplay-in-lightbox and start-muted toggles.
+- **Rebuild semantic index** maintenance action — fixes "dimension mismatch"
+  search errors after switching CLIP models.
+- Locate and filter images with failed AI-tagging jobs.
+
+### Changed
+- Gallery grid and Duplicate Finder list are now row-virtualised — large
+  libraries and large result sets (5,000+ pairs) scroll without lag.
+- Settings now open on General by default.
+
+### Fixed
+- **AVIF thumbnails** now generate correctly (routed through bundled FFmpeg);
+  previously-failed AVIF jobs are requeued on startup.
+- Video embedding jobs no longer churn through failed states before their
+  thumbnail exists; previously-failed ones are requeued.
+- Timeline scrolling is smooth on large libraries (per-row virtualisation);
+  background batches no longer re-sort the whole loaded set.
+- Numerous Subtle Light theme readability/parity fixes.
+
+See the [changelog](https://github.com/JezzWTF/phokus/blob/main/CHANGELOG.md)
+for the full list.
