1.x-1.4.1

Fixed

Saved token types load as objects: custom types show in the Token Browser, no PHP 8 warnings (#7, #6; PR #8 by dev-mm-distribution).
A token that contains itself, directly or via other custom tokens, is left empty and logged instead of crashing the page.
Delete button on the token and token type edit forms went to a broken confirmation path.
Token format column no longer defaults to php_code (update 1001).
Uninstall removes the whole token_custom.settings config file.

Changed

.info: dropped package = Core and the duplicate type line.
README: Token Filter recommended for the "Replace tokens" filter; dropped the Fast Token Browser recommendation (in core since 1.30.0); "AI Assisted" credit; Security section.
Docblocks in Backdrop format.

Removed

token_custom.features.inc: D7 Features integration, unused since 1.x-1.4.0 dropped hook_features_api().
