chore(privacy): scrub personal identifiers from public repo (#43)

Removes all occurrences of maintainer's real name and handle from
tracked files in this PUBLIC repository. Replaces with generic terms
like "project maintainer" / "the maintainer".

Files scrubbed:
- CLAUDE.md (2 instances)
- ALIGNMENT.md (Auditor field)
- docs/adr/0002, 0003, 0004 (Authors/Deciders fields + body text)
- memory/constitution.md (1 instance)
- docs/superpowers/plans/2026-04-10-lan-mode.md (Users/taodeng paths → $HOME)

Also:
- Replaces specific machine hostnames (Taos-Mac-mini, Taos-MacBook-Pro)
  with role-based names (home-mac, travel-macbook) in ADR 0001 (if
  committed; currently untracked).
- Replaces /Users/taodeng/ paths with $HOME/ in old plan doc.

NOTE: git history still contains the personal info. See postmortem
(issue TBD) for whether to rewrite history via git-filter-repo.
