[Feature Request] Allow ignoring folders/files while using Salesforce official PMD rulesets (e.g. AppExchange)

[jairzh]

Product Area

The "code-analyzer" CLI

Your Need or Problem

Currently, in order to exclude specific folders (such as test code) from PMD scanning, we must create a custom PMD ruleset and add entries.
However, this means we can no longer directly use Salesforce’s official rulesets (like the AppExchange rules). As a result, we lose the ability to automatically pick up new or updated rules when Salesforce updates its default rulesets.

Use Case
• We want to continue running sf code-analyzer run --rule-selector AppExchange to always benefit from the latest Salesforce-provided rules.
• At the same time, we need to exclude entire folders (e.g., /tests/, /mocks/) from being analyzed, without modifying or duplicating the official rulesets.

Your Desired Solution

Allow users to provide a global ignore list of folders/files (similar to .eslintignore) in code-analyzer.yml or via a CLI flag. This ignore list should be respected even when running Salesforce official rulesets such as --rule-selector AppExchange.
