Reverted: reject infeasible greedy final routes

[ShiboSoftwareDev]

Status: reverted

This fix has been fully reverted because preserving the hard crossing rejection in the final greedy route caused downstream autorouter benchmark samples to fail instead of producing routed output.

The current head has the exact same Git tree as reproduction base PR #155. The reproduction remains useful evidence, but this rejection behavior should not be merged without a recovery strategy that finds a valid alternative topology or assignment.

Benchmark This PR

Run benchmarks by commenting on this PR:

/benchmark [benchmark.sh args...]
/benchmark --dataset <hg07|srj18> --limit <n> --solver <core|poly> --families <default|default+deep|all> --concurrency <n|auto>

Everything after /benchmark is forwarded directly to ./benchmark.sh.
The result comment shows the matching dataset from the latest stored main-branch benchmark artifact beside the PR run; main is not rerun for each PR benchmark request.

Examples:

• /benchmark -> hg07, all samples, core solver
• /benchmark --dataset srj18 --limit 20 -> first 20 srj18 samples
• /benchmark --dataset srj18 --concurrency auto -> srj18 samples with runner CPU-count concurrency
• /benchmark --sample sample002 -> one hg07 sample
• /benchmark --limit 20 --solver poly -> first 20 hg07 samples with the poly solver
• /benchmark --limit 40 --families default+deep -> first 40 hg07 samples with deeper candidate families
