docs: describe right-to-left rendering in the manual and the invariants (release review)

The wiki gains right-to-left notes for Last Response, the phone's Compose
editor and the rendered Markdown view, plus a Troubleshooting entry for the
#715 report: the terminal is xterm.js, which has no right-to-left support
(xtermjs/xterm.js#701). src/web/CLAUDE.md and the invariants now state the dir
pins, the logical-property rule and that the direction pass runs last.

The changeset claimed every file path stays left to right. It now says only
what holds: the paths the viewer links on its own.
