Fix prospective Bifrost digest binding and preserve preflight claim

[DavidBakerEffendi]

The corrected Python control stopped before analyzer execution because the historical held-tool digest manifest still identified Bifrost v0.11.4. This prospective packet binds a fresh manifest for the exact public v0.12.0 binary and preserves the historical manifest.

Key Changes:

• Retain the failed preflight receipt and claim. Carry all 35 known predecessor claims and unknown historical counts into a disclosed new one-claim series; Python modeling remains first.
• Bind current Bifrost identity evidence while retaining the exact merged harness, runner, population, analyzer outcomes, deadlines and resource gates. All supplemental commands select the new packet.

Touch Points:

• reports/releases/v0.9.0/execution-v1/resume-20261007-04/python-preflight-failure-evidence/
• reports/releases/v0.9.0/execution-v1/resume-20261007-05/

Validation: the Python probe's read-only tool, CodeQL distribution and pack checks passed against the new manifest without analyzer execution; all 162 input bindings verified. Prior claim/anchor bytes are retained. No matrix execution, freeze or publication is claimed.
