[STYLE_bug] When styling does not find a box::use, all lines are converted into NA

[radbasa]

          @jakubnowicki Will need to go back to `box.linters::style_*`.

0.10.2 converts:

# View: Shiny modules and related code.
# https://go.appsilon.com/rhino-project-structure

to

NA
NA

We can do either of two things:

1. Implement and activate the exclude_files parameter of box.linters::style_box_use_dir()
2. Fix the bug converting the comment-only file to NA.

Recently this also happened when there was no empty line between box::use() and the rest of the code:

box::use(
  app/main,
)
context("Test main$format_duration()")
test_that("format_duration for NULL returns empty string", {
  expect_equal(main$format_duration(NULL), c(""))
})

Can you give me more details on how to reproduce this problem? I created a teste dir and the following file inside it:

# View: Shiny modules and related code.
# https://go.appsilon.com/rhino-project-structure
box::use(shiny)

# a
# b
1+1

Running box.linters::style_box_use_dir('teste') changed the initial file to

# View: Shiny modules and related code.
# https://go.appsilon.com/rhino-project-structure
box::use(
  shiny,
)

# a
# b
1+1

I added another file with the following content:

# View: Shiny modules and related code.
# https://go.appsilon.com/rhino-project-structure

# this file only contains comments!




# with spaces!

which was not modified with box.linters::style_box_use_dir('teste').
