fix(promotion): bind regenerated current view

[EffortlessSteven]

Summary

• retire the stale current-promotion binding consumed by PR docs(promotion): bind current control-plane state #394
• bind the regenerated current-promotion.md to exact swarm target 9d38e58
• preserve the source tree entry and explicit discard-source decision without changing authority policy

Why

The exact promotion planner rejected swarm/main because PR #394 regenerated current-promotion.md while the ledger still recorded its pre-#394 tree entry. This is the bounded ledger repair required for the exact current promotion target.

Proof

• cargo xtask promotion-state --check — pass
• git diff --check — pass
• exact planner dry-run against 9d38e58a885d214301bb494315882657e5e506de — pass
• two exact dry-runs — byte-identical
• prepared overlay — d230065609cc6f8d738d56017a48c4c37abb4f93
• path decisions — 41 total; 33 swarm overlay paths
• routed required check — run 30920560677, Shiplog Rust Small Result success

Claim boundary

This PR makes the promotion ledger truthful for the exact swarm target. It does not merge or publish the source promotion, create a tag, publish crates, or make a GitHub Release public.

Poem

A stale line hops out, a new line hops in,
The manifest ledger records where we've been.
PR #394 now sits on the vine,
Tree objects and SHAs all fall into line.
Thump thump — the promotion state's fine! 🐇
