feat(theseus+aegis): WizardConnect auto-detection — wiz:// links + page scan

Browse source 
Completes the three detection paths. The injected provider shipped in
0.8.8; these two needed host support, because nothing in the add-on API
could reach the active tab's content (captureTab is pixels, not DOM).

wiz:// links (main.js)
  A click on a wiz:// anchor is intercepted in will-navigate and in the
  window-open handler (target="_blank" lands there instead), and routed
  to the wallet with the offering page's origin attached, so the
  approval names the real site. The tab never navigates. This needs
  nothing from the dapp beyond rendering the URI as a link, so it works
  for third-party dapps that will never adopt a Silent Mode API.

scan-page capability (addons-host.js + main.js)
  New capability backing api.scanActiveTabForUris({scheme, limit}).
  Deliberately NOT a "read the page" API: the host runs the match and
  returns only the URIs found, so an add-on holding this still cannot
  see page text, markup or form values. It sits well below page-inject
  on the trust ladder — it learns that a page offers a wiz:// code and
  nothing else. Scheme is validated against [a-z][a-z0-9+.-]* and the
  result count is capped.

  The matcher also accepts WizardConnect's QR-alphanumeric spelling
  (WIZ://%3FP%3D…), which is frequently the only form present when a
  dapp renders its pairing code as a QR, and decodes it. Verified
  against the SDK: decodeKeyExchangeURI accepts standard, QR-raw and
  QR-decoded alike.

  Regex sources are built host-side and passed as JSON rather than
  assembled inside the injected string — hand-escaping backslashes and
  quotes through two levels of literal was both wrong on the first
  attempt and unreviewable.

Aegis
  Declares scan-page, adds the wcScanPage handler and a "Scan page"
  button next to Connect. A scan fills the URI field and stops there
  rather than pairing outright: the user still chooses which wallet
  signs and still presses Connect, because a scan that silently paired
  would carry far more consequence than the button implies. Older hosts
  without the capability get a clear "update Theseus" message instead of
  a dead button.
