djlint 1.46.3 on Python PyPI

A long run of unclosed {{ or {% no longer makes linting and formatting quadratic. Each was read again from every opener to the end of the line or the file, so eight thousand {{ on one line took over half a minute to lint and as long again to format, and twenty thousand in one attribute value took H054 alone 80 seconds; each now takes well under a second. A second opener is taken to mean the first one never closed, which is how the tokenizer already read them. T038 still reads an unclosed {% up to the next %}, as django does, so a run of those stays slow there.

A > inside a string of a template tag no longer ends the html tag around it when the string reuses the attribute's quote, as in class="{{ classes|default:"[&>a]:flex" }}". Before, the linter lost the rest of the tag, so H037 missed a repeated attribute after it, and the formatter put a line break inside the string.
H054 no longer reads an attribute out of a {# #} comment in another attribute's value, as in <a title="{# " href #}">, and leaves an input alone when an {% if %} writes its type and another tag writes the value, as in {% if shown %}type="{% if hidden %}hidden{% else %}text{% endif %}"{% endif %}.
A {# inside a {{ }} or {% %} tag, as in {{ "{# x" }} or an ICU message such as {n, plural, one {# item} other {# items}}, no longer opens a comment that runs to the next #} in the file. Before, the linter skipped everything in between, so T038 reported the {% if %} before it as unclosed and T041 missed an {% extends %} after it, and the formatter left the lines in between unformatted. A tag ends at its first closing delimiter, which is where django ends it.
