…readability (#20310) Builds on top of this PR: #20103 Adds some explaining comments and refactors the directive-scanning logic in the value injection loader from 4 functions down to 3 by inlining whitespace and comment skipping into the main loop. The previous implementation split the scanning into a separate `skipWhitespaceAndComments` function. The new version handles whitespace, line comments, and block comments as continue branches directly in the main while loop, which: - Eliminates one level of function calls - Unterminated block comments are handled inline with an early return - Makes the control flow easier to follow. Each iteration of the loop either skips something inert (whitespace/comments), successfully parses a directive and advances, or exits
