* http: realistic UA; fall back to WebPage on probe failure
Replace bare 'archivr/0.1' user agent with a full Chrome 131 UA string
(archivr/0.1 token retained at the end) in both probe_url_kind and download.
More importantly, stop hard-failing when probe_url_kind returns an error.
Sites behind Cloudflare's managed JS challenge (e.g. Medium) return 403
before any header tuning can help — a plain HTTP client cannot pass the
challenge. Instead, log a warning and fall back to Source::WebPage so that
the SingleFile/Chromium path gets a chance; a real browser can solve the
challenge transparently.
* capture: close dialog on Archive; rich per-URL and batch toast notifications
UX changes:
- Pressing Archive closes the capture dialog immediately; jobs continue
polling in the background (component stays mounted).
- Probe failures (e.g. Cloudflare JS challenge, HTTP 403) now fall back to
Source::WebPage so SingleFile/Chromium can attempt the capture instead of
hard-failing at the probe stage.
Toast notifications:
- Single URL: green 'Archived' on success, amber 'Archived with warnings'
(with expandable detail) when uBlock/cookie-ext was skipped, red 'Capture
failed' with expandable error text on failure. Per-item warning/error toasts
include the locator so the user knows which URL was affected.
- Multi-URL batch: per-item failure and warning toasts still fire with
locators; per-item success toasts are suppressed. Once all jobs settle a
single summary toast fires: 'N archived', 'N archived (M with warnings)',
'N archived (M with warnings), F failed', or 'N failed'. The summary Detail
section lists the exact URLs that failed or warned, so the user retains that
information after per-item toasts auto-dismiss.
- Batch summary color: green = all clean; amber = any warnings or failures
present; red = all failed.
- handleIgnoreUblock now only removes per-item warning toasts (those with a
locator) and persists the ignore flag; batch summary warnings (locator=null)
are not swept.
ToastStack improvements:
- All three branches (success/warning/error) support a toast.headline field
so batch summaries can set their own copy.
- Warning branch: Details button conditional on toast.text; Ignore button
conditional on toast.locator (uBlock-specific, not shown on batch summaries).
- Locator display uses hostname/…/last-segment for URLs (preserves domain for
context, tail for identity) and tail-truncation for shorthands; full locator
in title attribute for hover.
- Icon colors: green for success (✓), amber for warning (⚠), red for error (✕).
