feedback5: merge CB4 — community reports (enemies / bosses): a 突袭 member lands only on its own player's board (never a boss field's hand / 临时整备区 rows nor the other half of a 联防 or boss field), a silenced 萨卡兹枯朽战士 leaves no 污染秽蚀, 萨卡兹穿刺手's acceleration ends with a stun or 束缚 and its first hit after a block adds move speed × 600 as its own instance, 自制投石机 ignores its block when it picks a target (no attack on the 排气格栅's hidden blocker), the briefing types' 7–9 waves, 新硎's 断刃, a freed prisoner in 联防, 鸭爵's 0–2 swaps and the moving leaders' routes pinned, four reports not reproduced; §25.18; golden: vs feedback5 CB4's own rules — roster-016, boss-boss_2/3/4/5/6-pair, hidden-boss_8/10-pair, standin-04/06/08, diy-028, diy-124, matches solo-NORMAL-1, solo-HARD-1, solo-ABYSS-1, coop2-HARD-4, coop4-ABYSS-7, coop2-NORMAL-8-serverrun; vs CB4 exactly what feedback5 changed since its base (CB2's roster 13 / bonds 7 / fields 6, CB5's 18 bot matches)

Merge fix: test/sim/facing-invariance.test.js — the 突袭 rotation check put its enemy on the board's top row (9, 9),
so the facing-RIGHT landing tile it expected, (8, 8), lies above the player's board, where CB4's onOwnBoard rule (the
official 再部署 goes where the player deploys; community reports 40 / 16.3) now refuses it; the member landed on
(10, 8). The enemy stands at (10, 6), inside rows 9–12 / cols 2–10, so all four diagonal tiles are candidates in every
direction and the test checks the facing tie-break as before. It failed on fb5-cb4 itself (the stream did not run the
file). The §25 intro's stream lines joined into one sentence again.

Golden moves outside CB4's commit list are its rules on feedback5's paths (instrumented): solo-HARD-1 and solo-ABYSS-1
now have silenced 枯朽战士 deaths (8 / 15) and 突袭 candidates the own-board filter refuses; coop2-ABYSS-10-boosted,
coop2-NORMAL-3 and coop2-NORMAL-14-standins (in CB4's list) have no silenced 枯朽战士 death on this path, and their
digests are identical with the own-board filter switched off (the refused tiles were never the chosen ones).

typecheck ok, docs-consistency + docs-paths 31 / 31.
