ethernet 05c896cf52 ci: refactor paths & clones
ci: centralize path-gating behind single orchestrator + all-checks-pass
gate

Replace the scattered per-workflow detect-changes pattern with a single
ci.yml orchestrator that runs the classifier once, then conditionally
calls sub-workflows via workflow_call based on lane outputs. A final
all-checks-pass job (if: always()) aggregates all results so branch
protection only needs to require one check.

Changes:
- New .github/workflows/ci.yml orchestrator (detect + conditional calls
  + all-checks-pass gate)
- Extend classify_changes.py with scan/deps/mcp_catalog lanes, absorbing
  supply-chain-audit's internal changes job
- Update detect-changes/action.yml to expose the new lane outputs
- Convert all 10 PR-gated sub-workflows to workflow_call-only triggers,
  removing their push/pull_request triggers and per-step detect-changes
  guards (gating now happens at the orchestrator level)
- lint.yml + supply-chain-audit.yml receive event_name as a
workflow_call
  input to replace github.event_name (which is "workflow_call" inside
  called workflows)
- supply-chain-audit.yml: remove internal changes job + *-gate jobs
  (orchestrator handles gating, booleans arrive as inputs)
- contributor-check.yml: remove internal filter step
- Update test_classify_changes.py for 6-lane output + new supply-chain
  test cases

description: >-
Classify a PR's changed files into CI work lanes (python, frontend, site,
scan, deps, mcp_catalog) so the orchestrator can conditionally call only
the sub-workflows a PR can affect. Outputs are always "true" on push/dispatch
events and fail open (everything "true") when the diff cannot be computed.

# Only pull_request events are gated. Other events (push, release,
# dispatch) leave CHANGED empty, so the classifier fails open and every
# lane runs. Post-merge / on-demand validation is never weakened.

# Use the compare endpoint with the pinned base/head SHAs from the
# event payload instead of the "current PR files" endpoint. The SHAs
# are frozen at trigger time, so the file list is deterministic even
# if the PR receives a new push between trigger and detect.
