fix(plugins): refetch the registry manifest before install/update (#1380)

CHANGELOG.md

@@ -12,6 +12,10 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Fill Column: right-click a column header and choose Fill Column to set one value across all loaded rows. The change is staged like a normal edit, so you review it and Save before it applies, and one undo reverts the whole fill. Not available on primary key columns. (#1304)
 - AWS IAM authentication for PostgreSQL and MySQL connections to RDS and Aurora. Pick AWS IAM in the connection's Authentication field and use an access key, a named AWS profile, or SSO. TablePro generates a fresh login token on every connect and reconnect, so you never paste an expiring token, and SSL is required automatically. (#1291)

+- Installing or updating a plugin right after updating TablePro now refetches the current plugin list first, so it no longer fails against a stale cached list (the error a restart used to clear). (#1380)
