feat: TSCMono

[davidmh]

Exposes a new user command to run tsc in the monorepo mode.

We're making the following assumptions around the nature of a monorepo:

• When finding all the available tsconfig files, we're searching from the monorepo root.

• We find the monorepo root using the option monorepo_root_patterns, which is passed as the marker param to vim.fs.root, and defaults to { ".git" }.

  We're making it configurable in case someone uses some other vcs.

• Using each tsconfig directory as the project root

  When working on a monorepo, it's common to jump across projects, which can also mean changing the working directory in order to accommodate LSP clients, direnv callbacks, etc. See vim-rooter.

  That means that by the time we get the results from tsc, we might already be in a different working directory. Since the results from tsc use relative paths, the quickfix entries will be broken.

  To fix that issue, we're making all the project paths absolute, so we can:

  • Run each tsc command from its corresponding directory
  • Build an absolute path for the resulting errors

  That guarantees a valid file path in the quickfix, regardless of what the current working directory is by then.

Let me know what you think, open to suggestions!
