test(bench): add authoritative progressive run controller

[DecisionNerd]

Implements #956

Summary

• add one-command dry-run, native BenchExec rung, and S20 projection entry points
• bind exact source, executable, commit, profile, generator, and BenchExec identities in closed sanitized evidence
• enforce S18 then S19 ordering, schema validation, native cgroup authority, and first-failure refusal
• refuse real execution until the ordinary import-session path proves bulk construction and emits the complete progressive metric contract

Validation

• make -C benchmarks smoke (49 Python tests, Rust fmt/clippy/tests, dependency isolation)
• focused progressive controller tests: 7 passed
• ruff format/check and git diff --check

No real rung, provider, or Fly resource was launched. The canonical issue remains open for ordinary bulk-ingest repair and real S18/S19 evidence.

Walkthrough

The PR adds a fail-closed progressive qualification controller for native Linux BenchExec runs. It defines schemas for plans, results, and ingest capability, adds S20 projection support, exposes Makefile targets, and provides comprehensive tests.

Changes

Progressive qualification

Layer / File(s)	Summary
Qualification contracts and evidence fixtures benchmarks/schemas/*.json, benchmarks/tests/test_progressive_run.py	Adds strict schemas for run plans, failed results, and ordinary-ingest capability. Adds reusable GraphForge, BenchExec, and rung evidence fixtures.
Controller validation and plan construction benchmarks/harness/graphforge_bench/progressive_run.py, benchmarks/tests/test_progressive_run.py	Validates executable identities, Git commits, profiles, rung ordering, prior evidence, and serialized plans.
Admission and BenchExec execution benchmarks/harness/graphforge_bench/progressive_run.py, benchmarks/tests/test_progressive_run.py	Checks native Linux and ingest capability requirements, stages run inputs, invokes BenchExec, validates fixtures, and writes failed result evidence.
S20 projection and command wiring benchmarks/harness/graphforge_bench/progressive_run.py, benchmarks/Makefile, benchmarks/tests/test_progressive_run.py	Generates S20 projections from passed S18 and S19 evidence. Adds binary-build, planning, execution, and projection targets. Tests capacity validation and evidence output.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to eaa6d

The controller can produce evidence whose recorded executable bytes differ from the bytes actually run, and its result schema can accept failed records without the required source and executable identities. This can make benchmark results non-reproducible or unverifiable, so the PR is not merge-ready until these integrity checks are fixed or explicitly accepted by the owner.
