Remove explicit –config from RuboCop binstub templates
By removing the explicit config flag from the RuboCop binstub templates, this change allows RuboCop’s cascading config feature to work properly, enabling subdirectory-specific configurations.

Enhance rate limiting to support dynamic to: and within: options
This pull request changes the to and within options of the rate limiter to accept static values(as before), instance method names as symbols, and callables(lambdas/procs) that are evaluated in the controller context.

Optimize String#strip_heredoc
This pull request speeds up String#strip_heredoc by 1.5x to 5x when yjit is enabled. The new version doesn’t allocate any strings to find the minimum_indent to be stripped. Instead uses StringScanner#skip per each line to count whitespace char length.

Reset parallel test tables by deleting
With this change, on MySQL parallel test database table reset will use DELETE instead of TRUNCATE. Truncating on MySQL is very slow even on empty or nearly empty tables. As a result of this change auto increment counters are now no longer reset between test runs on MySQL and the SKIP_TEST_DATABASE_TRUNCATE environment variable no longer has any effect.
