update(procmon): fix windowed table follow-scroll & row sizing` (#340)

* update(procmon): fix windowed table follow-scroll & row sizing`

* Update plugin.toml

* Update README.md

* fix(procmon): always render list body as scroll to stop bottom clipping

0-result search switched the body from ui.scroll to a bare ui.row; when
results returned the row->scroll switch left the flexGrow viewport stuck
short, clipping bottom rows. Use ui.scroll with a shared key in both
branches so the tree keeps one stable scroll node.
