feat(coding-agent): added URL selectors with :raw and line range syntax to read command

- Added support for embedded URL selectors with `:raw` and `:L#-L#` line range syntax in read command.
- Implemented `parseReadUrlTarget()` function to parse and validate URL read targets with line range support.
- Updated read CLI to delegate URL inputs through read tool pipeline instead of treating as local file paths.
- Added comprehensive test coverage for URL selector parsing and CLI URL delegation.
- Refactored URL handling in read tool to use structured `ParsedReadUrlTarget` object.
