feat(edit): editing-conveniences pack (editops)
builtin/runtime/editops.lua: goto-line (M-g g / M-g M-g), case ops
(M-u/M-l/M-c), transpose chars/words (C-t/M-t), zap-to-char (M-z) +
zap-up-to-char, line move/duplicate/join (M-up/M-down/M-^), region
sort/reverse/dedupe, delete-trailing-whitespace + opt-in
trim_on_save. All edits ride the Q#EC2 guarded single-replace
discipline (snapshot, exact effective-triple check, context guard,
right-gravity transformed-cursor repair, unconditional selection
clear); word/case ops are explicit-byte-range ASCII (locale-proof);
transpose-words matches the empirical Emacs 30.2 boundary table.
killring.lua: zap commands join KILL_CHAIN; new exports kill_range
(validated, chain-aware, typed failure returns), break_chain([fid]),
and the Q#EC6 pending-prompt marker (arm/commit; arm-time
abandoned-marker break; kill_push force-fresh on an uncommitted
marker; detach cleanup) closing the silent-session-replacement hole.
Zap guards its origin frontend and re-verifies this_command at
accept time; commit_kill_prompt() reports armament so a consumed
marker fails closed.
editor.rs: editops.lua loader entry before saveplace.lua (the Q#EC9
before-save registration-order contract).
tests/editops_acceptance.rs: 68 dispatch-driven cases — RET/C-g
completed minibuffer sessions, the boundary-state pin, origin-guard
and silent-replacement matrices, the nine-position transpose table,
intercept discipline (reject/transform/context-switch/zero-length
anchor), trim sweep semantics, and trim-on-save veto interactions.
