Module warning_line 

Compiler-warning line writers for OffenderRecord batches.

Editor-friendly inline warnings: one offender per line, in the conventional Clang/GCC and MSVC formats that editor quickfix parsers (VS Code, IntelliJ, Vim) recognize out of the box. CI annotators do not auto-recognize these formats: GitHub Actions surfaces them only through a registered problem matcher, and other systems (GitLab, Jenkins warnings-ng) need an equivalent parser configured. This is the plain compiler-warning line; GitHub Actions’ own ::warning file=…:: workflow-command syntax is produced elsewhere, on the CLI annotation path (big-code-analysis-cli/src/check_format.rs), not by these writers.

Clang/GCC (write_clang_warning):

path/to/file.rs:42:5: warning: cyclomatic 17 exceeds limit 15 [big-code-analysis-cyclomatic]

MSVC (write_msvc_warning):

path\to\file.rs(42,5): warning : cyclomatic 17 exceeds limit 15

Both writers emit one line per offender. An empty offender slice produces empty output (zero bytes), not a blank line. Offenders whose path is not valid UTF-8 are skipped with a warning to stderr.
