The tag splitter matched ASCII ',' and ';' twice instead of the
fullwidth '，' (U+FF0C) / '；' (U+FF1B) the comment intended, so tags
separated by fullwidth punctuation (common under Chinese IMEs)
collapsed into a single tag.
Also resolves the compiler warnings surfaced in the same build:
- tiptap_bridge: drop unused Readable/Writable imports and
EditorInstance/TiptapEditorModule re-exports
- tiptap_bridge: migrate deprecated RequestInit::method/body/
credentials builders to set_method/set_body/set_credentials
- write: remove redundant `mut` on Dioxus signals that are only
read/set, never reassigned
- image_viewer: gate the server-only `mut` reassignment so the WASM
build (which strips the cfg block) doesn't warn
