Use @marko/parse for parsing

[DylanPiercey]

Replaces the vendored syntax tree builder with the new shared @marko/parse package (marko-js/language-server#586), the same CST used by the language server, eslint-plugin-marko and (pending) @marko/compiler. All 484 fixtures pass unchanged.

Depends on @marko/parse being published — the link: dependency needs to be swapped for a version range before merge.

Walkthrough

The plugin now uses the shared @marko/parse package for parser types, utilities, and parsing. The local parser module was removed. The package dependency changed from htmljs-parser to the linked @marko/parse package. Parsing clears root comments after parsing. Static-node formatting defaults missing targets to "static". A minor-release Changeset documents the migration.
