P3 cross-component stream-pair detection foundation + a fully
operational Mythos delta-pass auto-runner. 12 commits since v0.8.1.

Headline changes:

- Cross-component stream<T> pairing detection (#141, ADR-3). The
  StreamPairGraph foundation for the in-module stream adapter: meld
  now inventories at resolve time which fused components form
  producer -> consumer stream pairings. The ring-buffer / copy-chain
  emitter is a runtime-verified follow-up (ADR-3 Path N).

- Mythos delta-pass auto-runner (#162, #164, #170, #173, #175). The
  AI-driven discover protocol now runs automatically on every
  Tier-5 PR by the maintainer, via claude-code-action on a Max-plan
  OAuth token. Five plumbing fixes brought it to a working
  end-to-end state: scan -> NO_FINDINGS verdict -> sticky comment ->
  mythos-pass-done label.

- LS-N verification gate (#161, #165). Every approved loss-scenario
  in safety/stpa/loss-scenarios.yaml is now enforced to have a
  matching ls_<letter>_<num>_* regression test; 19/19 verified.

- DWARF / witness-mapping discovery (#131) — Phase 1 of the #130
  epic; pins today's lossy passthrough as the green-to-red oracle
  for the Phase 2 remap work.

- Regression coverage for LS-A-8/9/19 and LS-CP-4 (#163/165/166/169)
  — closed every missing-test entry the LS-N gate surfaced.

- CI footprint reduction (#171) — bench/fuzz/ci skip on docs- and
  safety-only PRs; meld is a leaner consumer of the shared fleet.

- fuzz.yml musl-target drop (#170, closes #168) — fixes the
  recurring "sanitizer incompatible with statically linked libc"
  fuzz failures.
