Subject: [PATCH] fix(repo): make IndexFile.Has() match exact version

Change Has() function to check against the exact version (as described
in the docstring comment) instead of falling back to the semver
constraints business. Fixes index merge in cases where version numbers
are similar enough (but not identical), causing previous entries to be
inadvertently overwritten.
