fix(gateguard): finish tool-agnostic checklist across edit gate and SKILL.md copies (#2274)

b3268fef (#2272) made the write-gate "confirm no existing file" item
tool-agnostic in the JS hook, but the rest of the checklist surface still
names Glob/Grep. On hosts without those tools the agent still hits a dead
tool call on:
- the edit-gate "list importers" item in the hook (scripts/hooks/gateguard-fact-force.js)
- both checklist items in all three SKILL.md copies (en, ja-JP, zh-CN)

Apply the same wording b3268fef introduced — "(search the tree — Glob/Grep,
or find/grep via Bash)" — to those five remaining spots so the whole gate is
consistent. Prose-only; no logic change.

Follow-up to #2272 / b3268fef.
