fix(hooks): 讓四支閘認得出「指令位置」跟「heredoc/引號裡的文字」

inkstone/InkStoneCo#23、#56 同一個病：閘對整條指令字串做關鍵字掃描，把「檔案內容/留言引用裡剛好提到某個關鍵字」當成「真的在執行」，同時放過包一層讀取指令、或藏在 heredoc body 裡的真動作。 - 新增共用輔助 hooks/lib/strip_heredoc.py：heredoc body 是資料不是指令，四支閘（github-contact / main-and-prod-push / stage-before-prod / kbdb-api-wall 的 Bash 分支）呼叫前一律先拿掉 body 再比對。 - main-and-prod-push-guard.sh：修掉跟 release-tag-guard.sh 同款的「開頭是讀取工具就整條放行」前綴繞過洞；git push 的偵測改成指令位置比對； main/master 目標改用單字邊界，不再誤中 "domain" 這種子字串。 - github-contact-guard.sh：拿掉 gh CLI／git push 判準裡「前面隨便一個空白就算數」的鬆散邊界，只認真正的指令分隔符。 - kbdb-api-wall-guard.sh：Bash 分支原本引用不存在的 kbdb_cmd_check.py， python3 找不到檔案就吃掉錯誤印 "OK"，該分支形同虛設——任何 `wrangler d1 execute` 直打 kbdb 都會被放行。邏輯搬進新檔 hooks/lib/kbdb_cmd_check.py（shlex 分詞、quote-aware），把 .sh 的參照路徑改過去，補回 Bash 分支的 kbdb-sql-ok 逃生口。四支各補 InkStoneCo#40 §1 要求的三行中文檔頭。新增四支可重跑測試（scripts/test-*.sh），共 69 條斷言全過，含 #23／#56 票上實撞的原始形狀（寫 docs/TESTING.md 的 heredoc、貼引用 #56 敘述的留言、`grep git push`）。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

+"""hooks/lib/kbdb_cmd_check.py -- shared helper for kbdb-api-wall-guard.sh's
+Bash channel (inkstone/ISEP#40 S7: helpers live in lib/, do not count as a
+hand-written gate).
+
+What it guards: whether a bash command string contains a real, at-command-
+position invocation of wrangler's D1 execute subcommand (any wrapper such as
+npx/pnpm) targeting a database whose name mentions "kbdb" -- that is a
+direct-SQL bypass of the KBDB API wall (D38, leo 2026-08-07: zero SQL,
+always through the HTTP API).
+
+Why this file exists (not just "why the rule exists"): the calling gate,
+hooks/kbdb-api-wall-guard.sh, used to pipe the raw command straight through
+a keyword grep. That produced the exact "keyword shows up vs. real
+instruction" confusion this repo has hit repeatedly (inkstone/InkStoneCo#23:
+the phrase showed up inside a delegation prompt that was *talking about* the
+rule, not breaking it). The fix pattern already proven on
+hooks/release-tag-guard.sh is "only count a keyword when it sits at command
+position" -- this file is that same pattern for the KBDB Bash channel,
+factored out to its own file because embedding shell-escaping-aware parsing
+inline in the .sh caused regressions each time someone touched it (see the
+.sh file's own header for that history).
+
+Two extra layers vs. a plain regex:
+  1. hooks/lib/strip_heredoc.py runs first (imported below) so a heredoc body
+     that merely *mentions* the D1-execute pattern against kbdb as
+     documentation text does not count -- same root cause as
+     InkStoneCo#23/#56.
+  2. Command segmentation uses shlex with punctuation_chars, so a `;`/`&`/`|`
+     that appears *inside* a quoted string (e.g. a commit message) does not
+     get treated as a command boundary, and text inside quotes is only
+     inspected when the quoted text is itself an argument to a command that
+     is genuinely at command position (e.g. a `--command` value passed to a
+     real wrangler invocation) -- not when it is merely quoted prose
+     describing the rule.
+
+Genuine parse failures (unbalanced quotes, exotic constructs) fail OPEN
+(print "OK"), matching this repo's stated design discipline: fail-open on
+parse failure, not fail-open on the verdict itself (see release-tag-guard.sh
+header). The caller (kbdb-api-wall-guard.sh) already blocks direct file-path
+writes into kbdb/ paths and DDL/`.prepare(`/`.exec(`/`.batch(` in Write/Edit
+content through its own separate channels -- this file only covers the Bash
+CLI channel.
+
+Usage:
+    printf '%s' "$CMD" | python3 hooks/lib/kbdb_cmd_check.py
