Overview

Recovers from wrecked bundler plugin state. Two wrecks are repaired:

A bundler plugin index entry whose stored path no longer exists. Bundler records absolute paths in .bundle/plugin/index for path-installed plugins. Moving or renaming the source directory leaves an invalid path behind -- Bundler::Plugin.load_plugin warns "The following plugin paths don't exist: ..." and silently returns, leaving @sources nil. The next source X, type: :vault crashes inside Bundler::SourceList#add_plugin_source with NoMethodError on nil. Uninstalling clears the broken entry.

A ghost specification: an installation record whose gem directory is gone (see Gemvault::GhostSpecification). Bundler's plugin installer trusts the record and validates plugins.rb against the missing directory instead of the copy it just installed, so every bundle install fails with MalformattedPlugin (issue #23). Removing the record lets the reinstall see the machine as it is.

Re-running bundle install afterwards triggers Bundler to reinstall the plugin against whatever the current Gemfile declares. Run this from the project directory.
