docs: reconcile bot-pipeline-unblock plan doc with shipped implementation

[bpamiri]

The design plan committed in #2847 (docs/superpowers/plans/2026-06-03-bot-pipeline-unblock.md) has two minor drifts from the merged code, flagged by Reviewer A. Both are cosmetic — the code is the source of truth — but worth tidying so a future reader isn't misled.

1. Every implementation step is - [ ] (unchecked) even though the work shipped. Via git blame / docs search this reads as a pile of un-done work. Fix: add a header note (e.g. > Implementation complete as of #2847; checkboxes left for historical fidelity) or bulk-check the boxes.

2. Allowlist description drifted. Under "Decisions carried from spec open-questions," the plan lists web/sites/*/src/content/** as low-risk. The shipped .github/scripts/classify-conflicts.sh dropped that arm — *.md/*.mdx (any path) already covers MDX content, and non-markdown files under content trees now correctly escalate. Update the plan's allowlist note to match, or add a "final implementation refined this — see classify-conflicts.sh" pointer.

Priority: low. Surfaced during the #2847 review cycle.

Docs scope

Two surgical edits to docs/superpowers/plans/2026-06-03-bot-pipeline-unblock.md to reconcile the plan doc with what actually shipped in #2847: (1) add a header note (or bulk-check the implementation checkboxes) so future readers can tell the work is complete rather than pending, and (2) update the "Decisions carried from spec open-questions" allowlist note to match the shipped .github/scripts/classify-conflicts.sh — which dropped the web/sites/*/src/content/** arm because *.md/*.mdx already covers MDX content and non-markdown files under content trees now correctly escalate.

Confidence: high

The target file is named explicitly, both fixes are described concretely with the exact text to change, the shipped code (classify-conflicts.sh) is the source of truth for the allowlist correction, and no design decisions are required.
