TranslateKit component stuck at 0.0.0.0 "Update error" on 151.0.4129.107 — on-device translation unusable (repros on Windows x64 and macOS arm64)

Summary
On Edge 151.0.4129.107, the Chrome TranslateKit component (the shared
engine all Translator API language pairs depend on) is stuck at version
0.0.0.0 with status "Update error" in edge://components, and never
successfully installs. MEI Preload is stuck the same way. As a result
Translator.create() never succeeds for any language pair, even ones
whose language packs show "Installed" in
edge://on-device-translation-internals.

Environment

• Machine A: Windows, x64, Edge 151.0.4129.107 — was working before
  updating to this version, broke immediately after
• Machine B: macOS, arm64, Edge 151.0.4129.107 — same failure
• Same two components (Chrome TranslateKit, MEI Preload) fail on both,
  everything else in edge://components is up to date

Steps to reproduce

1. On 151.0.4129.107, open edge://components
2. Check "Chrome TranslateKit" — version 0.0.0.0, status "Update error"
3. Click "Check for Update" — no change
4. Trigger Translator.create() for any language pair (e.g. via the
   Translator API) — hangs / never resolves to available

Expected
Chrome TranslateKit installs normally and Translator.create() succeeds
for available language pairs.

Actual
Component permanently fails to update; on-device translation is
completely unavailable.

Already ruled out

• Not a local profile/permissions issue — reproduces identically on a
  second, unrelated machine on a different OS and CPU architecture
• Not a network/firewall issue — reproduces on separate networks
• Full browser restart, "Check for Update" on the component, and a
  fresh profile do not resolve it

Impact
Any extension or site using the Translator API on this build gets no
on-device translation and silently falls back to server-side
alternatives, defeating the point of the on-device API for affected
users.

Start by reproducing the failure in edge://components on Edge 151.0.4129.107 and then trigger Translator.create() for an available language pair. Investigate the Chrome TranslateKit update error and verify completion when the component installs and Translator.create() succeeds.
