work-around: remove bundles directory

rm -rf bundles made the symptoms go away

[kriskowal]

The bundle read lock does not exist on the most recent releases of @endo/bundle-source. This might be solved by an upgrade.

ok... let's track this as a dapp issue, then:

[dckc]

The bundle read lock does not exist on the most recent releases of @endo/bundle-source.

I'd like to cite evidence of that and close this issue. I looked in the bundle-source changelog without luck.

Ah... I suppose this works:

Replaces the lockfile mechanism with atomic renames. -- https://github.com/endojs/endo/pull/1732

That suggests it's fixed in v2.80 2023-09-12.
