Local Dev cc563b0037 Theseus 0.0.4: cheap in-app update-check chip
Bumps version so the chip actually surfaces itself on 0.0.3 installs
(the version-newer check requires a strict semver bump — same-version
rebuilds don't trigger the chip). From this release on, whenever the
manifest names a newer Theseus, users get a one-click download.

Mechanism
- main.js checkForUpdate() fetches https://dl.silentmode.st/releases-
  manifest.json on startup (5s timeout, cache: no-store) + every 6h.
  Finds the theseus-navigator release, compares version to
  app.getVersion() with a numeric a.b.c comparator that handles
  "0.10.0 > 0.9.9" correctly.
- On a match → stores { version, setupUrl, portableUrl, setupHash,
  portableHash, date } and emits update-available to chrome. Cleared
  after the user upgrades + relaunches (same-version → null).
- Re-emits on chrome's did-finish-load in case the fetch beats the
  chrome view.

Chip UI (chrome.html)
- Acid-yellow pill between the downloads button and the Tor toggle:
  "↓ Update to X.Y.Z" + a ✕. Main body opens setupUrl in the system
  browser via shell.openExternal (origin-validated to
  https://dl.silentmode.st/ or https://silentmode.st/). ✕ dismisses
  for the current session — you'll see it again next launch if still
  behind.

Trust anchor
- No signing / no cryptographic verification of the download in this
  phase. releases.silentmode.bch publishes the SAME manifest URL, so
  users who want to verify can cross-check the manifest hash against
  what BCNR returns. The proper auto-updater with signature checks is
  the follow-on to this cheap version.

Non-goals in phase 1
- No delta downloads; the user clicks and gets a full installer.
- No auto-install; download → user runs the installer themselves.
- No "check now" button in Settings; the periodic timer suffices.
- No portable-vs-installed detection; the chip prefers setupUrl (the
  installer upgrades in place). Right-click for portable is future work.
