test: support Pi 1.0.2 HTML renderer callbacks

[yehezkieled]

Intent

Do not merge the worktree-trust fix (PR #2) past its failing check; fix the cause first. The failing check is CI shard "Behavior portable serial 6": tests/fm-calm-pi-extension.test.sh fails with "Pi calm renderer and lifecycle contract failed: grep disappeared from /export calm.html HTML while calm mode was on". CI installs @earendil-works/pi-coding-agent unpinned (.github/workflows/ci.yml around lines 118 and 222); the last green main run used 1.0.0 and Pi 1.0.2 was published 2026-10-04T00:56Z. The test passes locally with Pi 1.0.0.

What Changed

• Add getToolRenderers callbacks to calm export and branch HTML renderer test fixtures for Pi 1.0.2 compatibility.
• Retain getToolDefinition callbacks for compatibility with earlier Pi versions.

Risk Assessment

✅ Low: The bounded fixture update corrects the source-confirmed Pi 1.0.2 callback rename at every affected construction while preserving Pi 1.0.0 compatibility and existing behavioral assertions.

Testing

Inspected the test-only diff and ran both affected checks successfully, including existing native Calm E2E checks. Logs were retained in the evidence directory; no visual artifacts were captured. Pi 1.0.2 acceptance remains unverified.

• Live validation: ⚠️ no-surface - 0 of 2 scenarios driven live against the product
