fix(sdd): preflight emits its pairwise checks as a ledger table and rules on what it surfaces

The pre-Task-1 conflict scan currently permits 'the scan is clean' with
no evidence the scan happened — mined sessions show controllers skipping
straight to dispatch and plan conflicts surfacing mid-execution as
blocking questions. Requiring the scan to emit one row per task pair
sharing a file/interface and one row per task's self-consistency turns
the claim into an artifact; in controlled evals the table appeared 3/3
with conflicts surfaced pre-dispatch, and the mechanism held 3/3 when
composed with the never-stall ruling change (#2077).

 Superpowers is a complete software development methodology for your coding agents, built on top of a set of composable skills and some initial instructions that make sure your agent uses them.
 
 
-## We're Hiring!
-
-We're hiring someone to help out full time with Superpowers community and code work. 
-You can read about the job at https://primeradiant.com/jobs/superpowers-community-engineer/
-If this sounds like someone you know, definitely send them our way.

 ## Quickstart
 
 Give your agent Superpowers: [Claude Code](#claude-code), [Antigravity](#antigravity), [Codex App](#codex-app), [Codex CLI](#codex-cli), [Cursor](#cursor), [Factory Droid](#factory-droid), [Gemini CLI](#gemini-cli), [GitHub Copilot CLI](#github-copilot-cli), [Kimi Code](#kimi-code), [OpenCode](#opencode), [Pi](#pi).

-# Releasing to the Codex portal
-
-How to package a Superpowers release as the zip artifact OpenAI's Codex
-plugin portal expects, and what to check before handing it over.
-
-This is distinct from the older flow of syncing files into a fork of
-`openai/plugins` and opening a PR, which
-`scripts/sync-to-codex-plugin.sh` still implements — see the distribution
-table in [porting-to-a-new-harness.md](porting-to-a-new-harness.md). The portal
-artifact is a standalone, rootless archive: `.codex-plugin/`, `assets/`,
-`skills/`, `README.md`, `LICENSE`, and `CODE_OF_CONDUCT.md` sit at the
-archive root. Hooks, tests, docs, scripts, and other harnesses' manifests
-are deliberately not shipped.
-
-## Prerequisite: the OpenAI metadata source
-
-Each packaged skill must carry `skills/<name>/agents/openai.yaml`. That
-metadata is OpenAI-owned — it does not live in this repo — so the packaging
-script seeds it from a prior official package. By default it looks for, in
-order:
-
-1. `../_tmp/sup-codex-packaging/superpowers/` (an unpacked package)
-2. `../_tmp/sup-codex-packaging/superpowers.zip`
-3. `../_tmp/sup-codex-packaging/superpowers.tar.gz`
-
-or pass `--metadata-source <dir|.zip|.tar.gz>` explicitly.
-
-If you have no prior package on disk, extract one from `openai/plugins`
-(the upstream repo still carries the plugin, including the metadata):
-
-```bash
-# from a clone with an `upstream` remote pointing at github.com/openai/plugins
-git fetch upstream
-mkdir -p ../_tmp/sup-codex-packaging/superpowers
-git archive upstream/main -- plugins/superpowers |
-  tar -x --strip-components 2 -C ../_tmp/sup-codex-packaging/superpowers
-```
-
-**New skills fail the build.** The script requires one `openai.yaml` per
-skill directory; otherwise it prints `Missing OpenAI agent metadata for
-skill: <name>` for each gap and dies with `metadata source is incomplete`.
-If a release adds a skill, there is no metadata for it yet;
-you need an updated official package (or metadata added upstream in
-`openai/plugins`) before you can package. Don't hand-invent the yaml.
-
-## Build the archive
-
-From a clean working tree, package the release tag:
-
-```bash
-scripts/package-codex-plugin.sh --ref vX.X.X
-```
-
-The script reads the version from `.codex-plugin/plugin.json` (bumped by
-`scripts/bump-version.sh`, so it matches the release tag), stages the tree
-from the git ref — never from the working copy — and writes
-`../_tmp/sup-codex-packaging/superpowers-VERSION.zip`, printing entry
-count, skill count, and a SHA-256. Timestamps and file order are pinned so
-rebuilding the same ref reproduces the same archive.
-
-Useful flags: `--output PATH`, `--format zip|tar.gz`, `--allow-dirty`
-(archive still comes from `--ref`), `--keep-stage` (inspect the staging
-dir). `--help` has the full list.
-
-## Verify
-
-The script already refuses archives containing source-only paths and
-mismatched metadata counts. Sanity-check the result anyway:
-
-```bash
-unzip -Z1 ../_tmp/sup-codex-packaging/superpowers-X.X.X.zip | head
-unzip -Z1 ../_tmp/sup-codex-packaging/superpowers-X.X.X.zip | grep -c 'agents/openai.yaml'
-unzip -p  ../_tmp/sup-codex-packaging/superpowers-X.X.X.zip .codex-plugin/plugin.json | jq -r .version
-```
-
-Expect: rootless top-level entries (`.codex-plugin/`, `assets/`,
-`skills/`), one `openai.yaml` per skill, and the release version.
-
-The script itself is covered by `tests/codex/test-package-codex-plugin.sh`.
-
-## Upload
-
-Upload the zip through OpenAI's Codex plugin portal. This is a manual step
-outside this repo; record the SHA-256 the script printed so the uploaded
-artifact can be matched to the build.
