prosolis 2d249d7d0a Branching zones G5: navigation surface behind GOGOBEE_BRANCHING_ZONES=1 ...

Wires the graph types from G2/G3/G4 into the !zone advance flow.
Default off; with the gate on, room-clear branches on outgoing-edge
count instead of the linear current_room+1 walk.

zone_graph_nav.go — env gate, edge unlock evaluation
(LockNone/Perception/Key/LevelMin/RegionClear/StatCheck), pendingFork
JSON shape with encode/decode helpers, perception roll seeded
deterministically from (runID, from, to) so reload doesn't grant
retries, plus fork prompt rendering and the
recordRoomCleared/advanceZoneRunNode/completeRunAtNode persistence
trio.

dnd_zone_cmd_graph.go — advanceTransitionGraph drives the graph-mode
branch in zoneCmdAdvance: 0 outs → run completes (boss_defeated set
when current node IsBoss); 1 unlocked out → auto-advance and emit
the same teaser the legacy path uses; 2+ outs (or a single locked
out) → write pending fork to node_choices and render the menu. New
!zone go <n> / !zone choose <n> consumes the prompt, validates the
chosen edge is unlocked, advances, and emits the arrival teaser.
Old "go" alias for "enter" was unused in tests — repurposed.

dnd_zone_cmd.go — extracts formatNextRoomMessage so the legacy and
graph-mode paths share the post-advance teaser. Adds the new
subcommand to the dispatch switch and help text.

Tests: pure-logic coverage for unlock evaluation, perception
determinism, pendingFork roundtrip + decode-edge-cases, choice
resolution, fork prompt rendering with hint vs no-hint locked
options, edge ordering by (Weight, To), and the env gate. Existing
zone tests pass with and without the gate set.
