- Moves languages module from `zed` into a separate crate. That way we have less of a long pole at the end of compilation. - Removes moot dependencies on editor/picker. This is totally harmless and might help in the future if we decide to decouple picker from editor. Before: ``` Number of crates that depend on 'picker' but not on 'editor': 1 Total number of crates that depend on 'picker': 13 Total number of crates that depend on 'editor': 30 ``` After: ``` Number of crates that depend on 'picker' but not on 'editor': 5 Total number of crates that depend on 'picker': 12 Total number of crates that depend on 'editor': 26 ``` The more crates depend on just picker but not editor, the better in that case. Release Notes: - N/A
