Merge pull request 'feat(ext): verify cookies in-browser before uploading (1.0.7)' (#57) from dev into main

Pre-upload verify request: after capturing the live browser cookies,
hit a known authenticated endpoint with credentials:'include' from the
extension's background context. If the platform reports we're not
logged in, abort the upload so we don't overwrite FC-side credentials
with stale data.

- platforms.js: add `verify` config per cookie-auth platform
  - hentaifoundry: HEAD /?enterAgree=1 (mirrors gallery-dl's HF
    _init_site_filters; same 401 path the operator hit 2026-06-03)
  - patreon: GET /api/current_user (clean 401 when logged out)
  - subscribestar, deviantart: no stable auth endpoint, skip verify
- cookies.js: verifyCookiesForPlatform() returns {ok, status, reason}.
  ok=true/false/null tri-state — null = verify not configured, caller
  treats as "proceed".
- background.js EXPORT_COOKIES + EXPORT_ALL_COOKIES: verify gates the
  upload; failures bubble up with the platform's name + reason.
- popup.js: success message now appends "(verified ✓)" when applicable.
- manifest + package.json: 1.0.6 → 1.0.7.

+Audit 2026-06-02: the backend computes 13 ErrorType categories (auth_error,
+rate_limited, not_found, access_denied, validation_failed, etc.) and
+stamps each one on DownloadEvent.metadata, but the Source row only carried
+the free-text last_error. Operators couldn't bulk-triage failing sources
+("all auth_error → rotate cookies, all rate_limited → just wait") without
+opening Logs per row.
+
+This column receives the last error_type from _update_source_health
+and gets cleared on a successful run. Nullable + indexed so the failing-
+sources rollup can filter/group cheaply.

+"""Camie vocabulary -> human-readable tag-name normalization.
+
+Camie v2's ~57k tag vocabulary is booru-derived and arrives as raw
+strings like `uchiha_sasuke_(naruto)`, `#unicus_(idolmaster)`,
+`1000-nen_ikiteru_(vocaloid)`, or `:/`. We want the operator to see
+"Uchiha Sasuke", "Unicus", "1000-Nen Ikiteru", or to never see the
+emoticon at all — and we want the same clean string to be what lands
+in `tag.name` when the suggestion is accepted, so Accept matches the
+existing-tag convention (`tag_service.find_or_create`).
+
+Rules (operator-approved 2026-06-03):
+  1. Strip leading junk chars (#, ., +, ;, ~, _, whitespace)
+  2. Drop trailing `_(disambiguator)` block(s), iteratively
+  3. Strip wrapping single/double quotes (after disambig removal so
+     `"foo_em_up"_(series)` -> `"foo_em_up"` -> `foo_em_up`)
+  4. Replace remaining `_` with space; collapse runs of whitespace
+  5. Add a space after any `:` (namespace:tag -> namespace: tag)
+  6. Preserve hyphens (booru hyphens often carry meaning)
+  7. Title-case each space-separated word (first character only —
+     apostrophes, digits, hyphens stay)
+  8. If no letters AND no digits remain, return None (drops emoticons
+     like `:/` or `^_^`; preserves bare digit tags like `2005`)
+  9. No surname/givenname swap — no reliable signal in the vocab
