The memory/skill write-approval gate (#38199, #43354, #43452) was only
documented inside features/memory.md. Surface it everywhere users will
actually look:
- features/skills.md: new 'Gating agent skill writes' section under
skill_manage, with the staging semantics, review commands, and the
distinction from skills.guard_agent_created
- configuration.md: memory.write_approval added to the Memory
Configuration block; new 'Write approval for skill writes' subsection
next to the guard_agent_created scanner
- reference/slash-commands.md: /memory and /skills review subcommands in
both the CLI and messaging tables; Notes updated since /skills
pending/approve/reject/diff/approval now works on the gateway
- features/memory.md: cross-link to the new skills section
