Refactor panes and filesystem; replace FUSE with 9P

Consolidate pane, layout, memory and host code. Serve 9P by default over Unix sockets, with runtime mounts and optional TCP/QUIC transports. Remove FUSE and obsolete proof-of-concept examples.

Fix highlighting and terminal-history performance, expand differential and stress-test infrastructure, sort navigation results while preserving the next occurrence, add syntax-colored Braille minimaps, remove SPC-k, and document 9P interaction as a repository skill.

-# The acme INVERSION, end to end: while a script holds a pane's `event` file
-# open, a middle click in that pane is REPORTED to the script instead of being
-# executed by the editor. That is how an acme client defines its own commands —
-# `Step`, `Run`, `Clear` in examples/acmefs/life.py — and it is the one piece of
-# this filesystem that changes what a click MEANS.
-#
-# The clicked word is `Newcol`, a real pardes builtin, so the two halves of the
-# test cannot be confused with each other: with a reader attached the screen
-# must not change and the record must arrive; with the reader gone the same
-# click must open a column. It sits on the +New pane's first body line — row 5,
-# and the line-number gutter is 7 cells wide, so the word starts at column 8.
