* feat(docker): add opt-in sandbox support for Docker deployments
Enable Docker-based sandbox isolation via OPENCLAW_SANDBOX=1 env var
in docker-setup.sh. This is a prerequisite for agents.defaults.sandbox
to function in any Docker deployment (self-hosted, Hostinger, DigitalOcean).
Changes:
- Dockerfile: add OPENCLAW_INSTALL_DOCKER_CLI build arg (~50MB, opt-in)
- docker-compose.yml: add commented-out docker.sock mount with docs
- docker-setup.sh: auto-detect Docker socket, inject mount, detect GID,
build sandbox image, configure sandbox defaults, add group_add
All changes are opt-in. Zero impact on existing deployments.
Usage: OPENCLAW_SANDBOX=1 ./docker-setup.sh
Closes#29933

* fix: address code review feedback on sandbox support
- Persist OPENCLAW_SANDBOX, DOCKER_GID, OPENCLAW_INSTALL_DOCKER_CLI
to .env via upsert_env so group_add survives re-runs
- Show config set errors instead of swallowing them silently;
report partial failure when sandbox config is incomplete
- Warn when Dockerfile.sandbox is missing but sandbox config
is still applied (sandbox image won't exist)
- Fix non-canonical whitespace in apt sources.list entry
by using printf instead of echo with line continuation

* fix: remove `local` outside function and guard sandbox behind Docker CLI check
- Remove `local` keyword from top-level `sandbox_config_ok` assignment
which caused script exit under `set -euo pipefail` (bash `local`
outside a function is an error)
- Add Docker CLI prerequisite check for pre-built (non-local) images:
runs `docker --version` inside the container and skips sandbox setup
with a clear warning if the CLI is missing
- Split sandbox block so config is only applied after prerequisites pass

* fix: defer docker.sock mount until sandbox prerequisites pass
Move Docker socket mounting from the early setup phase (before image
build/pull) to a dedicated compose overlay created only after:
1. Docker CLI is verified inside the container image
2. /var/run/docker.sock exists on the host
Previously the socket was mounted optimistically at startup, leaving
the host Docker daemon exposed even when sandbox setup was later
skipped due to missing Docker CLI. Now the gateway starts without
the socket, and a docker-compose.sandbox.yml overlay is generated
only when all prerequisites pass. The gateway restart at the end of
sandbox setup picks up both the socket mount and sandbox config.
Also moves group_add from write_extra_compose() into the sandbox
overlay, keeping all sandbox-specific compose configuration together.

* fix(docker): ensure agent directory permissions in docker-setup.sh
* fix(docker): restrict chown to config-dir mount, not workspace
The previous 'chown -R node:node /home/node/.openclaw' call crossed into
the workspace bind mount on Linux hosts, recursively rewriting ownership
of all user project files in the workspace directory.
Fix: use 'find -xdev' to restrict chown to the config-dir filesystem
only (won't cross bind-mount boundaries). Then separately chown only
the OpenClaw metadata subdirectory (.openclaw/) within the workspace,
leaving the user's project files untouched.
Addresses review comment on PR #28841.
