v2.0.0

Breaking

• Require Node.js 22 or later #9. Dropped Node 20.

Fixed

• Log messages containing $1, $&, $$ and similar tokens are now emitted verbatim instead of being mangled as regex backreferences #8.
• %d placeholder now consistently returns a string.
• Corrected a "Could create the log message" fallback message that was missing the word "not".
• Pinned GitHub Action versions to SHAs #7.
• Refreshed dev tooling (ava, eslint, prettier and plugins) and migrated to native eslint flat config #10.
• Rewrote the README with install, usage, log levels, configuration and placeholder reference #10.
