Small cleanups from a pre-release review, one commit each:

• The CLI prints a loader error as one line instead of a traceback.
• The provider-name collision hint now suggests the inline {path, module} form; the old hint named a provider form that no longer exists.
• A wrong-shaped readme/license value raises TypeError, like every other field.
• A redundant assert in the regex plugin and a stale pylint ignore-paths entry are removed.

Not changed, for a decision: __version__ is still 0.5.0 with a v0.5.0 tag already on an earlier commit, and resolve skips the strict check when there are no entries.
