refactor(simulation): split the input.rs and dialogue.rs dispatchers (T-1062)

input.rs 2,739 → 858 lines: per-domain action handlers moved to their
owning modules (inventory, movement, stance, examine, follow, interaction,
save_io, settings, bridge::debug, economy, vision_cone, bookmark,
test_world reset + new teleport.rs); input.rs keeps the queue, the thin
dispatch table, and pause/cooldown glue. All 9 type_complexity allows
dissolved via one PlayerInputQuery alias.

dialogue.rs → dialogue/ directory module: selection (631), response
(1,473), confrontation (714), mod.rs (226, shared session components +
re-exports — public paths preserved). Documented seam deviation:
process_walk_away lives with confrontation (D-064/D-063 share the same
world-response shape).

Mechanical, zero behavior change: determinism + golden_suite byte-identical
(independently re-verified); 1,504 lib tests unchanged — 23 input tests
moved with their subjects, 53 dialogue tests redistributed, zero deleted.
System scheduling registrations untouched (input_plugin.rs 0-line diff).
