docuchat v0.3.2 — Uploads fixed + self-healing startup

Recommended update. If you are on v0.3.1, click "Update available" in the app to
install this in place. Everything from v0.3.0 (28 connectors, one-click updates)
is included.

Fixed: profile photo and document uploads

Uploading a profile photo or a document failed with "The string did not match
the expected pattern." The app's web view rejects a raw file as an upload body;
the app now sends the file's bytes, which works. Photo and document uploads work
again.

New: the app self-heals instead of getting stuck

If the Mac's Keychain key ever changes (after Migration Assistant, an OS
reinstall, or moving to a new Mac), the local data could no longer be unlocked
and the app would fail to start. It now detects this, sets the unreadable data
aside safely, and starts fresh, so a Keychain change can never lock you out.
Your existing data is never deleted.
