Resolves #136

Summary

Allow path segments beginning with a period (such as .well-known) in route matching and parsing without improperly stripping or rejecting them.

• Mangled leading period and underscore characters in generated filenames to prevent the Go build tool from ignoring compiled files.
• Guarded filepath extension trimming when the extension matches the full file name.
• Quoted literal path segments in route regular expressions to prevent unescaped periods from acting as wildcards.
• Tested in isolated container sandbox with zero regressions.
