Canonical market model and multi-format presentation architecture

[Tim55667757]

Goal

Establish the canonical market data model and presentation architecture for TKSBrokerAPI 2.x so domain logic can serve Python consumers, CLI workflows, reports, automation, and future integrations without format-specific coupling.

Scope

• Define the enriched provider-neutral market model.
• Separate query/projection contracts from presentation.
• Define stable machine-readable serialization contracts.
• Provide pluggable render/export adapters.
• Replace monolithic Overview-style reporting with composable projections.

Acceptance criteria

• Provider data is normalized into one reusable enriched market model.
• Domain calculations are independent from output formatting.
• Common projections can be consumed programmatically or rendered in multiple formats.
• Output adapters are replaceable and extensible.
• Legacy report structure does not constrain the canonical 2.x API.
