fix(cypher): 改用 global_fetch_strictly_public flag 解 same-zone 1042(revert service binding)

richblack 拍板:service binding(前一 commit)靜態、加/改要重 deploy cypher,廢。
改用 global_fetch_strictly_public compatibility flag——cypher wrangler.toml 加一行,
讓 fetch() 走公網前門,self-hosted 的 same-zone fetch(cypher 與 auth 同在
{sub}.workers.dev zone)也能通。

- wrangler.toml:compatibility_flags 加 global_fetch_strictly_public(移除 SVC_AUTH_*)
- auth-dispatcher.ts / types.ts:還原到 service binding 之前(單純 fetch workers.dev)
- 安全(官方 docs):唯一副作用 self-loop 僅在 fetch 自己 hostname;cypher 不 self-loop
- 官方/self-host 共用同一份 toml:官方本就跨 zone 行為不變,self-host 被修好
- 規範還原:rule 02/03/CLAUDE.md/pre-bash-guard 的 service binding 禁令維持原狀

SDD: credential-primitives-wasm Phase 7(A→廢→B)。tsc exit 0。
