Arc 1b phase 1 (framing: docs/lsp-panels-framing.md).
Q#P6 (the one Rust change): EditorCore.round_trip_buffers +
pmacs.buffer.set_round_trip_input(buf, on); dispatch_idle() reports
false while a marked buffer is active, so semantic frontends'
optimistic-apply stays off -- RET reaches a panel's buffer-local visit
binding instead of locally inserting a newline, and typing dispatches
into the edit path where the read-only intercept rejects it (a CRDT
import would bypass the intercept chain entirely). Pruned on kill.
Q#P1/P2/P3: builtin/runtime/listview.lua generalizes the *buffer-list*
idiom -- pmacs.listview.open{name, header, rows, on_visit, on_refresh}
owns ensure-buffer (recreates if user-killed), wholesale render with
bypass_intercept, line->item map, buffer-local RET/SPC/n/p/g/q keymap,
previous-buffer capture + q restore (never another panel; scratch
fallback), cursor re-seat after render, the read-only intercept, and
the Q#P6 mark. Panels are buffers: both frontends render them with
zero protocol change.
Q#P4: lsp.find-references (M-?) opens *references* -- one row per
location, paths shortened against the project root, RET visits via the
shared SP-4 template (jump ring, find_or_open, cursor walk; extracted
as visit_location for the phase-2 outline to reuse).
Acceptance: tests/listview_acceptance.rs -- open/seat/visit, header
non-visitable, q restore, read-only rejection, dispatch_idle gate,
refresh re-render + re-seat.
