Stop the bidi range at U+202E.

The range \x{202a}-\x{202f} also matches U+202F NARROW NO-BREAK SPACE. U+202A–U+202E are bidi formatting controls, while U+202F is legitimate whitespace used in locale data. This can create false findings for valid text. (unicode.org)

Change the range to \x{202a}-\x{202e} and add a fixture that accepts U+202F but rejects U+202A and U+202E.

In @.github/workflows/dogfood-gate.yml at line 118, Update the PATTERNS
definition to end the bidi-control range at U+202E by changing \x{202a}-\x{202f}
to \x{202a}-\x{202e}. Add or update the relevant gate fixture to verify U+202F
is accepted while U+202A and U+202E are rejected.

⚪ LOW RISK

Suggestion: The -r flag is redundant when used within find as the file traversal is already handled. Switching from {} \; to {} + will significantly improve performance by batching files into fewer grep process invocations. Additionally, removing the 2>/dev/null redirection is recommended so that potential regex syntax errors or execution limits are visible in the CI logs.

Suggested change
-exec grep -aPrl "$PATTERNS" {} \; > /tmp/empty-lint-results.txt 2>/dev/null
-exec grep -aPl "$PATTERNS" {} + > /tmp/empty-lint-results.txt
