chore(tooling): enforce no-floating-promises and drop DOM globals from Node-side typechecking (#104422)

* chore(lint): enforce no-floating-promises repo-wide

* feat(tooling): split DOM globals out of the Node-side typecheck program

tsconfig.core.json now compiles src/ + packages/ with lib ES2023; new
tsconfig.ui.json owns ui/ with DOM. Web-global names used by Node code
alias to canonical undici/stream-web types; highlight.js loads through a
validated narrow API because its d.ts force-includes lib.dom. Boundary,
sparse-guard, changed-lane routing, and profile lanes cover the new ui
graph.

* chore(deps): declare undici-types and teach knip about the highlight.js runtime require

* ci: retrigger dropped pull_request synchronize event

* refactor(types): derive web-global aliases from @types/node fetch globals, drop undici-types dep

* ci: retrigger after dependency guard cleared

* fix(scripts): add ui lane to changed-lanes declaration union
