In the past we had logic to automatically set the search context to the current topic during the tutorial. This hasn't worked for a long time, and clearly people have still been able to complete the tutorial. In fact, it's probably better for us to teach people how to use the search un-assisted anyway.
This commit removes the dead logic, and makes a slight tweak to the copy in the unlikely event of confusion.
Why this change?
Instead of manually loading files, we should just structure the plugin
so that it relies on Rails autoload strategy and avoid all the manual
`require_relative`s.
What does this change do?
1. Structure the plugin to use Rails autoloading convention
2. Remove onceff jobs that were added 5-6 years ago. There is no need to
carry these jobs anymore after such a long time.
3. Move setting of `SiteSetting.discourse_narrative_bot_enabled` to
`false` in the test environment from core into the plugin.
This commit removes any logic in the app and in specs around
enable_experimental_hashtag_autocomplete and deletes some
old category hashtag code that is no longer necessary.
It also adds a `slug_ref` category instance method, which
will generate a reference like `parent:child` for a category,
with an optional depth, which hashtags use. Also refactors
PostRevisor which was using CategoryHashtagDataSource directly
which is a no-no.
Deletes the old hashtag markdown rule as well.
