Pipelock was removed in PR #193. Update the five remaining places
where current documentation (README, examples/bottles/claude.md,
tests/README.md, docs/ci.md, sidecar_bundle.py comment) still
described the old pipelock + cred-proxy topology.
- Strip pipelock from all unit and integration test fixtures:
proxy_plan fields removed from DockerBottlePlan/SmolmachinesBottlePlan
constructors; pipelock-specific test classes deleted or renamed
- Update test_sidecar_init: remove test_pipelock_loses_egress_tokens,
rename "pipelock" daemon fixtures to "git-gate" throughout
- Remove test_pipelock_binary_present_and_versioned from integration test
- Remove test_pipelock_answers_on_bundle_ip from smolmachines launch test
- Update _SANDBOX_BLOCK_MARKERS: remove "pipelock" marker (egress blocks)
- Dockerfile.sidecars: remove pipelock build stage and COPY; update layout
comments and port table
- egress_entrypoint.sh: update comments now that egress is sole proxy
- Clean up pipelock references in comments/docstrings across backend,
network, manifest, supervise, git_gate, yaml_subset, agent_provider,
sidecar_bundle, sidecar_init, egress_addon_core modules
