What if we did what we do for .bidsignore and pull it out of the tree? We don't need a filesystem hit to check if it's there.

Suggested change

	const defaultConfig = join(absolutePath, '.bids-validator-config.json')
	try {
	await Deno.lstat(defaultConfig)
	config = JSON.parse(Deno.readTextFileSync(defaultConfig))
	options.config = defaultConfig
	} catch {
	if (!(err instanceof Deno.errors.NotFound)) {
	throw err;
	}
	}
	const configFile = tree.get('.bids-validator-config.json') as BIDSFile
	if (configFile) {
	config = await configFile.text().then((text) => JSON.parse(text))
	}

We could also use our JSON loader and create an issue. Probably better not to crash...

Similarly:

Suggested change

	let config = {}
	const configFile = dirHandle.find(file => file.name ==='.bids-validator-config.json')
	if (configFile) {
	config = configFile.text().then(text => JSON.parse(text)).catch((err) => {
	alert(`Failed to load ".bids-validator-config.json". \n\nUsing empty configuration object:\n\n${err}`)
	})
	}
	const fileTree = await fileListToTree(dirHandle)
	const fileTree = await fileListToTree(dirHandle)
	let config = {}
	const configFile = fileTree.get('.bids-validator-config.json') as BIDSFile
	if (configFile) {
	config = await configFile.text().then(text => JSON.parse(text)).catch((err) => {
	alert(`Failed to load ".bids-validator-config.json". \n\nUsing empty configuration object:\n\n${err}`)
	})
	}

Oh, and we probably need to add .bids-validator-config.json to our default ignores.
