Ship Theseus 0.0.5 606529ea (search fix + link-hover status bar)

Setup   606529ea9f1de9dc1ec5012534dda31b06919245f19f934ee1b9f4f10385a5bc

Fixes:
- Classic form-GET search engines (Google, Brave, Bing, Startpage,
  Yandex, Ecosia, Mojeek, ...) now show results. The tab's
  will-navigate intercept was dropping the query string on every
  dotted-host navigation, so /search?q=foo landed on /search. DDG
  only appeared to work because its in-page search uses pushState +
  XHR and never triggered will-navigate.
- Address bar reflects the target URL immediately on Enter instead
  of showing the previous page's URL until did-navigate fires.

New:
- Link-hover status bar: Firefox / Chrome-style pill at the bottom-
  left of the window showing the href when the pointer is over a
  link, hidden when it leaves. Auto-sizes to text, cleared on tab
  switch, tracks window resize.

Also on-VPS: bns-gateway auto-index directory paths (f43ec61) so
silentmode.bch/tools/ returns the tools page instead of NoSuchKey.

Deployed:
- scp installers + releases-manifest.json to /opt/silent-mode/dl/
- scp tools/index.html + releases/index.html to /opt/silent-mode/site/
- sia-upload of ../site to bns/silentmode/
- verified: HEAD 200 on both installers, manifest reports 0.0.5,
  silentmode.st/tools shows the 0.0.5 buttons, Sia mirror ditto.

The 0.0.4 update-check chip should now surface itself for existing
installs on their next launch.
