* fix(app): jump the chat outline to prompts a timeline plugin draws
A timeline transformer replaces a stream item with plugin rows whose ids
are "<pluginId>/<itemId>". The chat outline, chat find and history reveal
look a message up by the source item's id, so once a plugin drew the
prompts the outline found no row: the rail showed the prompts and
clicking one did nothing, for mounted, virtualized and unloaded prompts
alike.
Projected plugin rows now carry the id of the item they replaced, and
getStreamItemMessageId answers with it. Row wrappers, the virtualized
index lookup, the visible-message set and history reveal all read that
function, so they now find the plugin row.

* test(app): verify outline jumps to virtualized plugin prompts
Replacing every prompt keeps all loaded rows mounted, so the original plugin regression never exercised a virtualized target. Retain newer native prompts and verify that a loaded unmounted plugin prompt lands without fetching.

Send every original tool call and each whole accumulated assistant message through plugin transformers before display grouping or Markdown splitting. Preserve streaming callbacks, original payloads, native Markdown block identities, and chat outline reading position. Reject legacy fragment caches and retain failing-first plugin-interface and browser regressions.
Fixes#4673. Fixes#4789. Consolidates #4820.
