test(coverage): ratchet autogen branch coverage gate

[OgeonX-Ai]

Summary

Implements the Phase 26-02 coverage ratchet for autogen and records the verified local gate results.

Changes

• updates the pytest coverage command to enforce total coverage at 73
• adds branch coverage telemetry enforcement at 54.6 from coverage.xml
• adds focused tests for maf setup and phase 3 routing paths
• aligns requirements with the verified repo-local virtualenv stack

Why

Phase 26-02 requires a measurable branch coverage ratchet backed by repo-declared dependencies and local verification evidence.

Validation

• repo-local .venv full suite passed with coverage
• total coverage reached 73.26 percent
• branch coverage reached 54.65 percent
• pip check passed

Risks

• fresh scratch install no longer has the earlier resolver conflict, but a full install was not proven end-to-end before timeout
• remote CI still needs confirmation on this PR

• root planning phase 26-02

Use a cross-platform shell for telemetry

This job still runs on windows-latest, and this step does not override the default shell; GitHub's workflow syntax docs state that an unspecified Windows run step uses pwsh, while this python - <<'PY' heredoc is Bash syntax, so the Windows matrix leg will fail parsing the telemetry step even when tests pass. Set shell: bash for this step or use shell: python/a script file instead. See GitHub docs: https://docs.github.com/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepsshell
