Fix quoted paths in options strings

Pull request overview

This PR improves how user-configured option strings (Pandoc options and Docker options) are converted into argument arrays by adding a quote-aware parser, so paths/options containing spaces can be passed correctly without shell interpolation.

Changes:

• Added parseShellArgs() to split option strings while preserving quoted substrings.
• Updated Pandoc and Docker option handling to use parseShellArgs() instead of whitespace splitting.
• Updated the built dist/extension.js to reflect the new parsing behavior.

The new argument-splitting behavior is central to this change (quoted paths/options), but there are no tests asserting the resulting argv. Please add unit/integration tests that cover common cases like --resource-path="/a b", mixed quoting (e.g. --opt=foo"bar baz"), and Docker options containing quoted values, to prevent regressions across platforms.
