Use the WebKit preview without isFunctionInSource()

Have the ranges of Profiler.takePreciseCoverage nest as the source does, with nothing after the last statement of a block

Bump the transpiler cache version for the new mappings, and delete the input line count that only the old coverage read

Use the WebKit preview that leaves the end offset of a label to parseStatement()

Test what is after a function in a block that did not run

Use the WebKit preview where what is after a statement goes up to the end of its list

Take the mappings of a SourceMap with get_stringish_allow_empty(), so that a symbol has the error it had

Keep the layout of the header of InternalSourceMap, which the Bun of another version reads in a compiled executable

Use the WebKit preview where the end offset of a block is after its brace

Merge remote-tracking branch 'origin/main' into claude/bun-coverage-source-mapping-df389a

Use the WebKit where the basic blocks of the control flow profiler match the text

Test a do while that is the body of an if and a file with nothing to run
