PR-1c: Compiler.run(target=) kwarg threading — InitialProg.target + KernelCtx.target#80

Adds the target dispatch hook required by Phase B2 work without changing render behavior. `Compiler.run` accepts `target='cuda'` and exposes it on `compiler.active_target` for the duration of the call; `InitialProg` and `KernelCtx` gain a `target: str = 'cuda'` field; `VerifyRenderabilityShim` reads `state.target` instead of the hardcoded literal. Defaults preserve byte-equivalence on every existing call site. Per docs/phase_decomposition_redesign.md §2.3 (target monopolization) and §3.3.1 (target chosen at run time). Per-target render dispatch itself lands in Phase B2-2. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Third of 5 splits of the original PR-1. Plumbing-only — threads
target: str = 'cuda'through the compile pipeline so Phase B2-2 (multi-target render dispatch) has the dispatch authority hook to wire to. Per spec § 2.3 + § 3.3.Compiler.run(prog, *, pipeline, target='cuda')accepts the new kwarg; restored via try/finally (exception-safe)InitialProg.target: str = 'cuda',KernelCtx.target: str = 'cuda'(both frozen dataclass field additions)VerifyRenderabilityShimreadsstate.targetinstead of hardcoded'cuda'literal'cuda'everywhere — preserves existing call-site behaviorTest plan
D10 confirmation
LowerCtx(src/srdatalog/ir/core/lower_ctx.py) already pins 5 fields includingtarget(pre-PR-1c addition). PR-1c threadstargetvia carrier dataclasses + a transientCompiler.active_targetattr — never touchesLowerCtx.Out of scope (later splits)
