D4 Stage B — complete Autoflow integration

[LogicDuke]

D4 Stage B clean replacement.

This PR supersedes the fragmented Stage-B delivery previously spread across
PR #74 and PR #77, but those PRs remain preserved until this replacement
completes validation and review.

This replacement was rebuilt from exact main:

58f1dcb

It contains one coherent 16-file Stage-B candidate:

Runtime / tests:

• serialized Autoflow ingestion through D1
• Cockpit snapshot schemaVersion 2
• required autoflow semantics
• hostile-input reconstruction via readWorkflowState
• prototype-hook insulation
• repositoryId binding
• D4 read-only projection
• host Autoflow rendering
• focused and adversarial regression coverage

Architecture contracts:

• D1 synchronized with schema v2 / required Autoflow
• D3 synchronized with current D4 projection + host behavior
• D4 synchronized with current D1 ingestion + host integration
• remaining deferred workflow/reviewer features remain deferred

Authority remains unchanged:

• AgentBridge remains read-only
• Autoflow remains workflow authority
• Cockpit observation grants no transition authority
• no Policy authority
• no provider authority
• no repair authority
• no Ready authority
• no merge authority

Independent validation:
