Organize control-plane and canary smokes

[huangruiteng]

Summary

• move 65 control-plane runtime smoke scripts into examples/control_plane/
• move 4 canary-promotion smoke scripts into examples/canary/
• update canary planner/runner/docs/catalog references for the new paths, including control-plane/control_plane module matching
• calibrate current work-lane/status smoke expectations for the monitor schedule-metadata repair contract and update the Python line-budget pins to current main facts

Validation

• PYTHONPATH=. python3 -m py_compile loopx/canary/runner.py loopx/canary/planner.py tests/test_smoke_suite.py examples/control_plane/work-lane-contract-smoke.py examples/control_plane/repo-python-line-budget-smoke.py
• moved control-plane batch: PYTHONPATH=. python3 -m loopx.cli --format json canary smoke-suite --suite full-public <65 moved scripts> --timeout-seconds 120 --no-progress -> 65 selected / 65 executed / 0 failures
• canary module: PYTHONPATH=. python3 -m loopx.cli --format json canary smoke-suite --suite full-public --module canary --timeout-seconds 120 --no-progress -> 10 selected / 10 executed / 0 failures
• control-plane preview: PYTHONPATH=. python3 -m loopx.cli --format json canary smoke-suite --suite full-public --module control-plane --no-execute --no-progress -> 74 selected / 0 warnings / 0 unsafe
• full control-plane module execution still has 2 pre-existing semantic reds outside the moved batch: examples/mini-control-plane-interrupt-comparison-summary-smoke.py and examples/mini-control-plane-repair-with-interrupt-smoke.py
• git diff --check and git diff --cached --check

Notes

The moved control-plane and canary batches are green. The remaining mini-control-plane-* reds are left as a separate canary triage item rather than hidden in this organization PR.

Self-merge review note after owner authorization.

Findings: none blocking.

Product/architecture judgment:

• Motivation: reduce examples/ root sprawl and make control-plane/canary smoke suites selectable by module without losing the existing runner payload.
• Solved: the PR moves 65 control-plane and 4 canary-promotion smokes into subdirectories, updates catalog/docs references, and keeps loopx canary smoke-suite as the source of truth.
• User/operator impact: easier local module execution, less noisy examples root, and clearer canary/refactor ownership for future smoke triage.
• Main risk: broad path churn plus small canary runner module-matching change. Risk is bounded by moved-script suite validation and no benchmark runner/scoring behavior changes.
• Design judgment: path organization plus runner aliasing is a reusable catalog/module boundary, not a one-off patch. The two remaining mini-control-plane-* reds are classified as separate semantic triage, not hidden by this PR.

Validation:

• GitHub Frontstage Pages build: pass after rebase onto latest main.
• git diff --check origin/main...HEAD
• PYTHONPATH=. python3 -m py_compile loopx/canary/runner.py loopx/canary/planner.py examples/control_plane/work-lane-contract-smoke.py examples/control_plane/repo-python-line-budget-smoke.py examples/canary/canary-promotion-readiness-smoke.py examples/canary/canary-promotion-readiness-boundary-smoke.py examples/canary/canary-promotion-no-write-contract-smoke.py examples/canary/canary-promotion-readiness-writeback-smoke.py
• moved control-plane batch: 65 selected / 65 executed / 0 failures
• canary module: 10 selected / 10 executed / 0 failures

Merge decision: self-merged with explicit owner authorization and admin bypass for review requirement.
