Enhance build system and integration with Tact compiler

[novusnota]

Generally:

1. Set makeprg to match builds with and without Blueprint
2. Set errormsg to match error messages coming from those builds.
3. Fill quickfix list with messages from the compiler (and provide better tools/mappings for using this list), see: https://github.com/vim/vim/blob/v8.2.5172/runtime/doc/quickfix.txt

Also, try adding new commands related to Blueprint and its integration into the pipeline.

Additionally, consider using @tact-lang/compiler or its CLI for:

1. Inference and suggestions
2. Error handling
3. Builds

(Optional) Introduce an auto-generation or basic help with tact.config.json. Suggest using JSON Schema.

P.S.: npx tact --check
