Blueprint class

A project blueprint containing deterministic creation details.

Binds: FR-021–FR-026, INV-B1/B2/B3 (schema 1) and FR-022–FR-027, INV-B4–B7 (schema 2, contracts/blueprint-schema-v2.md).

Schema 2 replaces the flat fixed-stack fields (recipeId, recipeVersion, integrations) with structured singleSelections/multiSelections. Both shapes live on one class — not a distinct BlueprintV2 type — so every consumer (compatibility, resolution, plan) forks on nothing but schemaVersion. The v1-only fields stay required-free (defaulted) purely so v2 construction sites don't need to supply them; every existing v1 call site is unaffected. toJson/fromJson are schema-dispatched: a schema-1 Blueprint round-trips through the unchanged v1 shape (existing callers — including the doctor toolchain probe, which relies on recipeId/engineVersion equality checks — see zero behavior change); a schema-2 Blueprint serializes to exactly the v2 contract shape, with no v1 fields in the output (B-4). The schema_version: 1 → 2 auto-upgrade migration rule (FR-048–FR-050) is separate from this raw parse — it lives where the CLI reads external input (T054), not here, so this factory's existing round-trip behavior for schema 1 remains exact.
