docs: the ⌘K palette description matches what it actually offers (BEA-84) (#132)

README.md:499 promised "share/history/upload actions" in the command
palette. Upload has never existed there (browser upload is deliberately
absent, Browser.tsx:175), download went unmentioned, and share/download
are file-scoped — so a reader on a folder route goes hunting for controls
that are correctly hidden. The doc comment at Palette.tsx:8 carried the
same wrong list, so fixing only the README would leave the next reader of
the component with the same picture.

Prose and a comment only; no code path changes. `npm run build` produces
a byte-identical internal/webapp/static (source comments are stripped
from the bundle), so no assets to commit.
