* Create scorecard.yml

* fix: FORBID_TAGS must win over ADD_TAGS function predicate (#1230)

Mirrors the FORBID_ATTR early-exit pattern (c361baa, line 1214) for
FORBID_TAGS. When EXTRA_ELEMENT_HANDLING.tagCheck is a function that
returns true, the short-circuit evaluation previously skipped the
FORBID_TAGS check, allowing forbidden elements through.

Moves FORBID_TAGS[tagName] to an OR at the top of the condition so the
removal block is always entered for forbidden tags regardless of the
tagCheck predicate result.

* fix: apply SAFE_FOR_TEMPLATES scrub in RETURN_DOM path (#1241)

The RETURN_DOM path returns before the final template expression
scrub, allowing split mustache expressions to reconstruct after
element removal. Normalize adjacent text nodes and scrub body
before building the return node.

* fix: prevent ADD_ATTR/ADD_TAGS function leaking into subsequent array-based calls (#1242)

When sanitize() is called with ADD_ATTR or ADD_TAGS as a function, the
function reference is stored in EXTRA_ELEMENT_HANDLING. A subsequent call
that passes ADD_ATTR/ADD_TAGS as an array did not clear the stored function
because objectHasOwnProperty(cfg, 'ADD_ATTR') returned true, skipping the
conditional reset.

The leaked function is evaluated before URI/tag checks, so a permissive
function (returning true) lets dangerous attributes (e.g. javascript: URIs)
or forbidden tags (e.g. iframe) through on later calls.

Fix: unconditionally reset tagCheck/attributeCheck to null on every
_parseConfig() call, then only set them if the current config provides a
function. This ensures no cross-call leakage.

Includes regression tests for both ADD_ATTR and ADD_TAGS leakage scenarios.
