Description: Teaches the shared inline-expectations test library to describe source edits for codeql test run --learn. When a tagged inline-expectation postprocessor finds mismatches, it emits a learnEdits relation that the matching CLI support applies to the annotated source file. Without --learn, ordinary expectation comparison is unchanged. Rendering learned expectations The library emits 1-based edits using the engine protocol: appends at the end of a line and half-open replacement ranges [startColumn, endColumn), with endColumn == 0 meaning through end of line. Learning supports line-comment expectations. ExpectationComment.isLineComment() lets each language adapter identify comments that are safe to rewrite. Existing block comments, including JSX {/* $ Alert */} comments, are left untouched. The append logic also declines to append beside an excluded line comment, where the new text would otherwise become part of that existing comment. The renderer can keep, remove, rewrite, or append standard expectation tags; promote MISSING: results into expectations; remove SPURIOUS: expectations; and preserve unrelated tags, query qualifiers, and trailing comment text. API and metadata TestPostProcessing::InputSig supplies start and end comment markers by source file, leaving room for future languages whose comments require closing delimiters. ExpectationComment supplies isLineComment() across the language adapters. Standard inline-expectation postprocessor queries, including both Actions variants, carry the inline-expectation-test tag required by the CLI. Follow-ups Rendering block-comment expectations for XML, YAML, HTML, JSX, ERB, Razor, and similar inputs. Reconciling multiple queries that share a source file, such as Alert[query1] Alert[query2]. Splitting comma-separated shorthand when only one tag needs updating. Supporting inline-expectation tests that do not use a .qlref postprocessor.
