Restore the relationship lore graph work (revert of #24)

[mcfarhat]

Reverts #24, restoring the #21 work that was merged at 19:02 and reverted at 20:52. This is correcting my mistake, not Kareem's.

What happened

Kareem merged #21 himself after I approved it. That was the wrong call — merging is the reviewer's — and he opened #24 to revert it, which was the right instinct. I verified that revert was exact and approved it, on the reasoning that it would return develop to its pre-merge state and clear the conflicts the out-of-order merge had created on #22 and #20.

It did the opposite. Reverting a merge commit leaves the branch's commits as ancestors of develop while removing their content. Measured after #24 landed:

                     before #24    after #24
#22 conflicts             5            9
#20 conflicts             4           10
#21                   mergeable    UNMERGEABLE  ("Already up to date", content does not return)

I checked the resulting tree matched the pre-merge commit — it did, byte for byte — but merge behaviour follows history, not content, and I didn't check that. So #21 became impossible to re-merge, and every file #22 and #20 share with that stack started looking deleted-on-develop.

What this PR does

The documented git fix: revert the revert. Verified before opening:

• lore.ts and the rest of the stack are restored
• resulting tree is byte-identical to a64edb4, the state immediately after Feature/m2 relationship lore graph kareem #21 merged
• with this applied, Hive broadcast reliability #22 returns to 5 conflicts and feat(ui): add contribution editor workflow #20 to 4 — the conflicts that always existed between those PRs, not ones we manufactured

Where that leaves sequencing

#21 lands first, which isn't the order I wanted, but undoing it costs more than accepting it. #22 still merges next — onto a develop that already contains #21 — and #20 after that. The original reason for the ordering (#22 carries the migration baseline repair and the test harness) still holds and is unchanged by this.

No code is modified. This is purely a history correction.
