+ * Convert a filesystem path to forward slashes.

+ * ts-morph stores source-file paths internally with forward slashes and

+ * `path.resolve()` return backslash-separated paths, which causes
+ * ts-morph to silently fail to find any files (resulting in 0 functions
+ * extracted). Always normalise to forward slashes before handing paths

+ *
+ * UNC paths (`\\server\share\...`) are correctly converted to
+ * `//server/share/...`, which TypeScript understands on Windows.
+ *
+ * CONTRACT FOR CONTRIBUTORS: every path that will be passed to ts-morph
+ * (addSourceFileAtPath, getSourceFile, etc.) or stored as a functionId
+ * component MUST go through toPosixPath() first. This applies to the
+ * result of any path.resolve(), path.relative(), or path.join() call.
