bug: window-local terminal options leak into :edit-replaced buffers

• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

NVIM v0.13.0-dev-110+g8603fc9180

Operating system/version

26.3.1

Describe the bug

When I run :edit somefile from a Sidekick CLI buffer, the new file buffer reuses the same window and inherits Sidekick’s terminal-specific window-local options, so number, relativenumber, signcolumn, and statuscolumn stay disabled in the file I just opened. This seems specific to Sidekick rather than terminal buffers in general, since the same flow does not reproduce with a plain Neovim :terminal; Sidekick appears to apply terminal UI options to the window but does not restore them once that window stops showing the Sidekick terminal buffer.

Steps To Reproduce

1. Open a sidekick cli buffer
2. Perform :edit some-file.md

Expected Behavior

I'd expect the window/buffer to not inherit the sidekick options, and instead utilize what my normal neovim config does.

It should work how neovim does with general terminal buffers.
