feedback2 docs: DESIGN §22 intro and §22.7–§22.13; 余 S2's deviation listed with §21.29's six

The §22 intro maps GitHub #25 … #35 / #16 to §22.1–§22.13 and records the owner's decisions of 2026-10-04.
§22.7–§22.12 are the wave-2 subsections verbatim; §22.13 is PR #48 (要塞 cannot hit air units, 莫斯提马's slow shows its icon).
One blank line before every §22 subsection, as in §21.

余 S2 (SKILL_RANGE on its x-1, §22.10) is appended wherever the six-skill deviation is listed: DESIGN §5.6, §20.2, §21.20, §21.29,
DATA §2 item 6, research 00 and 03 (SKILL_RANGE counts: 13 / 26 official, 14 / 28 in the data). DATA §2.1 names 要塞 in canHitFly.
