TextForSpeech v0.17.2

What changed

preserved cwd and repoRoot shortening for markdown inline code spans that contain file-line references such as /repo/Sources/Foo.swift:12
narrowed embedded-code path routing so slash-operator snippets like a/b stay in the generic code-speech lane instead of being misclassified as file paths
added focused regression coverage for inline file references and inline slash-operator markdown spans

no caller-side API changes are required for this release
maintainers should keep treating embedded markdown file-path detection as a narrow path-specific lane rather than a blanket rule for any slash-containing token
