fix(local): stop proposing per-dependent patches for dependency-cascade failures
The `--open-issue` run proposed 800+ entries, all `rcppparallel-bundled-tbb` on ubuntu-2604, each pre-filling `RcppParallel/disable-tbb.patch` for an unrelated package (ACEsimFit, AovBay, ...). Those packages fail only because their RcppParallel *dependency* does not build there, so bincraft records RcppParallel's TBB error text against each dependent and they all match the signature. Applying a RcppParallel source patch to a dependent's source is not just noise -- it is broken (the diff targets RcppParallel's Makevars.in). Add an optional `applies_to` field pinning a package-specific fix to the package it targets. A signature whose fix is a curated per-package source patch (rcppparallel-bundled-tbb -> RcppParallel) is only ever proposed for that package; other matching packages are downstream failures reported as "blocked on <dependency>" and never proposed a bogus entry. Fix the dependency once and the whole cascade clears. - gate proposal generation in build_triage_report on applies_to, add blocked_on - surface blocked groups in the report and proposer instead of a misleading "already registered" note - cover both the dependent-blocked and RcppParallel-itself-proposed cases
