Why:
- Obsidian's plugin checks were reporting compatibility and packaging warnings that could break popout-window behavior or leave async failures unhandled.
- The build also depended on a deprecated module listing package and carried inline tests that leaked warning noise into the production bundle.
What:
- add @codemirror/view as a runtime dependency and replace builtin-modules with node:module builtinModules in the esbuild config
- route plugin async startup and save-file hooks through compatibility helpers so delayed work uses window.setTimeout and fire-and-forget promises are explicitly handled
- switch the AI progress notice to activeDocument, await clipboard writes, align extended Obsidian types, rename the settings heading, and remove unused catch bindings
- move trie inline tests into dedicated Vitest files and add coverage for the new compatibility helpers to keep the build warning-free
