Discovering running Biome servers...

Incompatible Biome Server: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

i Rage discovered this running server using an incompatible version of Biome.

Server:
  Version:                      <=10.0.0

What happened?

Given the following files:

// biome.json
{
	"$schema": "https://biomejs.dev/schemas/1.0.0/schema.json",
	"organizeImports": {
		"enabled": true
	},
	"linter": {
		"enabled": true,
		"rules": {
			"recommended": true
		}
	},
	"vcs": {
		"enabled": true,
		"clientKind": "git",
		"useIgnoreFile": true
	}
}

// ignore-this/file.ts
debugger;

biome ci . when .gitignore contains ignore-this:

biome-ignore-bug on  main [?] via  v18.16.0 
❯ pnpm biome ci .
Checked 1 file(s) in 2ms

...when .gitignore contains:

• ignore-this/ (trailing slash)
• /ignore-this (leading slash)

biome-ignore-bug on  main [?] via  v18.16.0 
❯ pnpm biome ci .
.\ignore-this\file.ts:1:1 lint/suspicious/noDebugger  FIXABLE  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  × This is an unexpected use of the debugger statement.

  > 1 │ debugger;
      │ ^^^^^^^^^
    2 │ 

  i Suggested fix: Remove debugger statement

    1 │ debugger;
      │ ---------

.\ignore-this\file.ts lint ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  × The file contains diagnostics that needs to be addressed.


Checked 3 file(s) in 4ms
Found 2 error(s)
ci ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  × Some errors were emitted while running checks.

Expected result

Since the above cases are all ignored by git, I would expect biome not to error.
