Tests cover block-tag exclusion (with both true/false conditions),
plain text line exclusion, nested block exclusion, custom exclude
patterns via coverage config, and self-closing tags like {% cycle %}
that should not be treated as block openers.
Allow users to exclude template lines from coverage using Django comment syntax. A pragma on a block-opening tag excludes the entire block (including nested blocks) through its matching closing tag. A pragma on a plain text or variable line excludes that line only. Uses coverage.py's report:exclude_lines patterns, so the default pragma: no cover works with zero configuration and custom patterns defined in .coveragerc / pyproject.toml are picked up automatically. Block openers are identified by a forward look-ahead for a matching end tag, so self-closing tags like cycle, load, and url are never mistakenly treated as block openers.

This PR implements
pragma: no coverfor templates. I tried to mirror the same behaviour used in Python; when declared on a block, the entire block is excluded. When declared on a single line / not a block tag, only that line is excluded. The implementation supports theexclude_linesandexclude_alsocoverage.py report settings.Example:
I tried keeping iterations to a minimum. I evaluate the tokens as list prior to the for loop to support a lookahead search for nested closing tags.
