Ship Theseus 0.3.29 ea51507c (fix Aegis card IPC-shape crash)

Setup    ea51507c94b4ccb1a2e9048aea21a433803d3ac41ea31531c86efef75d9d27dc
Portable 571a31046abc83eef6b23494bbd38e98bb79a1b51812d2c0e1cc303aadbc8e12

Bundled since 0.3.28:

4c55f04 - Aegis update card in Settings > General was showing 'Status
check failed: installed.find is not a function'. Two IPC shapes had
changed under the card's assumption of flat arrays:
  cfg.listAddons()         → { installed:[…], sidebarPanels:[…] }
  cfg.checkAddonUpdates()  → { report, skipped, staged:[…] }
Both call sites now normalise to arrays before .find(). Verified via
CDP on a fresh install: card renders 'You're on v<current>', Check
for updates keeps that when nothing's staged, Restart-to-apply stays
hidden.

920febb - package-lock.json version-field bumped 0.3.16 → 0.3.22 to
match what npm install had already written (housekeeping, no deps).

Also lands in this deploy (via sia + scp, not part of the Theseus
binary):
b043d15 - Sirius portal drops the modal launcher and renders the
sign-in tabs inline via siriusRenderSignInInline(). One flow, no
popup, refresh-safe.

Deployed. Verified LIVE 0.3.29.
