fix(hygiene): clear all 22 dead §33 migration xrefs (perpetual non-required-check)

[AceHack]

Summary

The lint (§33 migration xrefs) check has been firing as a non-required failure on every PR this session (PRs #3626, #3628, #3631, #3636, #3639, #3641, #3646, #3647, #3650, #3652, #3653, #3654, #3657, #3661, #3662, #3663). Root cause: the docs/research/ → memory/persona/otto/conversations/ migration (B-0533) left 22 dead references across 18 files.

Mechanical bulk fix: 12 unique target filenames substituted in-place in 18 source files. Each substitution is docs/research/<NAME>.md → memory/persona/otto/conversations/<NAME>.md for a SPECIFIC filename (no blanket replacement of docs/research/ — only the 12 known-migrated filenames).

Verification:

• bun tools/hygiene/audit-section-33-migration-xrefs.ts --enforce was 22 dead xrefs before this commit, 0 dead xrefs after
• Pure-substitution diff: +22/-22, no content changes
• All 12 target files verified to exist in memory/persona/otto/conversations/
• ls-tree canary clean (53/53 root entries)

Files changed

18 files changed, 22 insertions(+), 22 deletions(-)
- 1 .claude/rules/claim-acquire-before-worktree-work.md
- 6 docs/backlog/P*/B-*.md (B-0003, B-0061, B-0239, B-0313, B-0400, B-0001, B-0196, B-0002 — 8 backlog rows total; some have 2 hits)
- 9 memory/feedback_*.md
- 1 memory/CURRENT-aaron.md
- 1 memory/user_*.md

Remaining drift

The other 4 perpetual non-required-check failures remain:

• lint (backlog ID uniqueness) — B-0498 collision already scoped at B-0545
• lint (tsc tools) — needs separate investigation
• check docs/BACKLOG.md generated-index drift — needs regen pass
• check MEMORY.md generated-index drift — needs regen pass

Test plan

• audit-section-33-migration-xrefs.ts --enforce returns 0 dead xrefs (was 22)
• Pure-substitution property: 12 sed expressions, each scoped to a specific filename
• Pre/post-commit ls-tree canary clean (53/53; Lior gone)
• CI green (docs-only; expect lint (§33 migration xrefs) to FLIP from fail → pass)

Pull request overview

This PR fixes the perpetual lint (§33 migration xrefs) failure by updating stale cross-references that still point at docs/research/<NAME>.md to instead point at the migrated archive location memory/persona/otto/conversations/<NAME>.md.

Changes:

• Updated 22 xrefs across memory files, backlog rows, and a .claude/rules doc to the post-migration archive paths.
• Kept changes scoped to specific known-migrated filenames (no blanket docs/research/ rewrite).
• Updated memory/CURRENT-aaron.md and related memos to reference the new archived conversation paths.
