Make the one-off tool control explicit.

.claude/CLAUDE.md does not require declared dependencies or bunx --no-install --bun for one-off tools. Add this rule to keep tool execution within the dependency and lockfile controls.

In @.claude/CLAUDE.md at line 118, Update the Bun guidance in the runtime and
package-management table to require one-off tools to be declared dependencies
and executed with `bunx --no-install --bun`, preserving the existing
package.json and bun.lock controls.

🟡 MEDIUM RISK

Suggestion: Since Deno is being replaced by Bun as the Tier 1 runtime, it should be explicitly listed in the Banned table to clarify the policy transition and prevent its accidental use.
