chore: update biome configurations and applied settings

[theorderingmachine]

Summary

• upgrade @biomejs/biome to the current v2 line
• migrate biome.json to Biome 2 config format
• apply Biome 2 formatting / organize-imports changes across source, tests, and examples
• clean up a few newly-flagged example-code and suppression warnings so Biome 2 passes cleanly

Validation

• biome check docs src test examples
• npm run build
• npm run test:types
• npm run test:coverage

Notes:

• On this NixOS host, npm run lint still tries to execute the vendored Biome binary from node_modules, which is dynamically linked and not runnable here.
• Validation was done with nixpkgs#biome for the lint-equivalent check instead.

@theorderingmachine LGTM! Lots of reorderings of imports but this is a good change I think.

📚 https://biomejs.dev/guides/upgrade-to-biome-v2/

Will merge this with tests passing and research in comments to unblock #2854.

📚 note: Our examples use handfuls of unused variables with intention so we ignore some rule for now to avoid more changes:

bolt-js/examples/socket-mode/app.js

Lines 59 to 63 in c8de330

	// Message Shortcut example
	app.shortcut('launch_msg_shortcut', async ({ shortcut, body, ack, context, client, logger }) => {
	await ack();
	logger.info(shortcut);
	});

🌲 praise: Thanks latest update!

🔭 note: We might be confident in these reorderings with the following reference:

If there are two wildcard exports statements that implicitly re-export the same name, neither one is re-exported.
