feat(openclaw): add Feishu approval worker skills

[GatewayJ]

Summary

• Add an OpenClaw worker lark-cli skill for Feishu app binding, user OAuth, diagnostics, and CLI execution.
• Add a feishu-approval skill for initiated approval queries, approval details, and guarded resubmission workflows.
• Normalize approval query output and OpenClaw lark-cli config handling so agents can use minimal permissions with fewer manual steps.

Impact

• New OpenClaw worker agents can use Feishu/Lark approval workflows from the embedded skill template.
• Approval record queries request only approval:instance:read and show status labels instead of raw status codes.
• PicoClaw and Codex templates are not changed by this PR.

Validation

• go test ./internal/templates ./internal/agent
• python3 internal/templates/embed/openclaw-worker/workspace/skills/skill-creator/scripts/quick_validate.py internal/templates/embed/openclaw-worker/workspace/skills/lark-cli
• python3 internal/templates/embed/openclaw-worker/workspace/skills/skill-creator/scripts/quick_validate.py internal/templates/embed/openclaw-worker/workspace/skills/feishu-approval
• bash -n internal/templates/embed/openclaw-worker/workspace/skills/lark-cli/scripts/*.sh internal/templates/embed/openclaw-worker/workspace/skills/feishu-approval/scripts/*.sh
• python3 -m py_compile internal/templates/embed/openclaw-worker/workspace/skills/feishu-approval/scripts/format_initiated.py
• Verified the approval list script inside the running OpenClaw container returns normalized JSON with items[] and status_label.

Notes

• This PR is opened as draft for review of the skill wording and OpenClaw worker template scope.
