feat: keyboard navigation for tag suggestion dropdowns

Tab/ArrowDown cycles through suggestions, Enter selects the active one,
ArrowUp goes backwards, Escape dismisses. Works on browse filter inputs,
upload page, image detail page, and image viewer tag editor.

feat: add weimar image rescan-innate CLI command

Adds ListAllImages and UpdateImageInnateTags DB queries, and a
rescan-innate subcommand that computes innate tags for all images
missing them — useful after upgrading from an older version.

feat: add innate tag system for media characteristics

Automatically assigns tags based on file type, dimensions, and video
duration: "image"/"video"/"gif"/"lowres"/"highres"/">10 sec"/"<10 sec".
Stored as JSON in images.innate_tags, searchable via tag filter,
clickable in UI with distinguished blue styling, and included in
tag autocomplete suggestions.

feat: use full-resolution download URL for og:image previews

Images now point to the original file instead of the 300px thumbnail,
giving Discord/Telegram the highest quality preview frame. For videos,
the thumbnail is kept as a static poster since the download is a video
file. The body image in the OG page uses the same URL.

feat: Open Graph link previews for image and video pages

Serves a static HTML page with full OG meta tags at /image/{id} for
social media crawlers (Discord, Telegram, Twitter, etc.). Real
browsers are redirected to the SPA via a script tag.

- og:title, og:description, og:url, og:image, og:image:secure_url
- og:type, og:locale, twitter:card=summary_large_image, theme-color
- og:video tags for video files with twitter:player for Discord embeds
- X-Forwarded-Proto support for reverse proxy HTTPS detection
- Canonical share URL changed to /image/{id} in the browse viewer
- Comprehensive test proving all required tags are served

fix: resolve Svelte a11y warnings and unused CSS

Replace non-interactive `<li role="button">` with proper `<button>`
elements in all suggestion lists (upload, detail page, ImageViewer).
Replace `<li role="option">` with `<button role="option" aria-selected>`
in browse page filter dropdowns. Remove unused CSS selectors.

test: add tests for uploader filter, tag+uploader combo, and user suggestions

Also fixes a bug in ListImages where placeholder args were in the wrong
order when both tag and uploader filters were combined.

feat: autocomplete suggestions for tag and uploader filters

Tag filter shows usage count, uploader filter shows upload count.
Both endpoints use requireAuthOrPublic for unauthenticated browse.
200ms debounce on input. Backend uses LIKE prefix match ordered by
count descending.

feat: filter images by uploader with clickable uploader names

Adds `?uploader=<username>` query param support to GET /api/images.
Uploader names are clickable throughout the UI (browse cards, viewer,
detail page) to filter the gallery to that uploader's media.

feat: full-screen drag-and-drop upload zone

Document-level drag events trigger a full-screen overlay with dark
backdrop and dashed red border, accepting the file on drop
anywhere on the page. File can still be selected via button click.

fix: graceful SIGINT shutdown and SIGHUP config reload

SIGINT now exits cleanly with code 0 instead of propagating
http.ErrServerClosed as a fatal error. SIGHUP re-reads the config file
and atomically swaps the config pointer — settings like site_title,
favicon_path, behind_proxy, and require_auth_for_browse take effect
immediately without restarting. Config is stored as *config.Config
throughout so handlers and middleware read the live value at request time.

feat: configurable site title, favicon, and nav logo

Add site_title, favicon_path, and logo_path config options. Default favicon
is an embedded SVG with a red lowercase "w" on black. Custom favicons can
be SVG, PNG, JPG, or ICO — the /favicon handler serves them with the
correct Content-Type detected from the file extension. The /logo handler
serves a nav logo; when set, the layout shows an <img> instead of the text
site title. The GET /api/config endpoint exposes these URLs to the frontend.
Includes example config at configs/example.toml.

fix: security hardening — bcrypt cost, secure cookies, security headers, avatar auth

Bump bcrypt cost from 10 to 12 for adequate brute-force resistance in 2026.
Add behind_proxy config option that enables Secure flag on session cookies
for deployments behind a TLS-terminating reverse proxy (Caddy, nginx).
Add X-Content-Type-Options, X-Frame-Options, and Referrer-Policy security
headers to every response. Fix avatar endpoint auth mismatch — avatars are
now served publicly since their URLs are exposed in gallery listings anyway.

feat: public browsing, shareable image URLs, and tag editing

Public browsing is the new default — unauthenticated users can browse the
gallery, view images, and download originals. Lock it down by setting
`auth.require_auth_for_browse = true` in weimar.toml.

Each image now gets a shareable URL when opened in the overlay viewer:
`/browse?image=<id>`. Navigate to it directly and the viewer opens
automatically (or redirects to the detail page if the image is on a
different page).

Image owners can now edit tags from the overlay viewer or the detail page.
A text field with autocomplete and ADD/REMOVE buttons appears below the
tag display on your own uploads.

Backend: new public/optional auth middleware, AddImageTags/RemoveImageTags
queries, is_owner field on image detail, require_auth_for_browse config
option. Frontend: viewer tag editing, shareable URL via pushState, image
detail page uses is_owner from backend instead of separate getMe() call.

Replaces full-page navigation with a Chevereto-inspired lightbox overlay

after 3s of inactivity, and a bottom info bar with metadata and download.

fix: preserve all tags on upload and return empty array on no match

Tags beyond the first were silently dropped because `r.FormValue("tags")`
returns only the first value when the frontend sends each tag as a
separate FormData field. Changed to `r.Form["tags"]`.

Nil slices in API responses (`var images []Image`) marshalled to JSON
`null`, causing a TypeError in the Svelte template (`null.length`),
making "Loading..." persist forever. Initialized all API-facing slices
with `make()` so they marshal as `[]`.
