claude: back up custom skills, memory, and settings with symlink pattern

The ~/.claude/ directory was previously local-only — a machine wipe
would have lost the accumulated memory, custom skills, and settings.
This commit moves the durable parts into dotfiles with the same
symlink-to-home pattern used for CLAUDE.md, PENDING.md, REVIEWED.md,
and L2-BOOTSTRAP.md.

Preserved (symlinked from ~/.claude/* into here):
  skills/audit/              — thinking-folder drift scanner
  skills/symmetria/          — practice-of-return discipline
  skills/vault-update-people/ — Obsidian People-file maintainer
  skills/wake-up/            — session restoration
  skills/wrap-up/            — session state capture
  memory/                    — 55+ memory files (MEMORY.md, sessions,
                               ledgers, project state, feedback, etc.)
  settings/settings.json     — user preferences (hooks, flags, no secrets)

Deliberately NOT backed up:
  settings.local.json   — contains operational secrets (HF_TOKEN,
                           SSH password in expect scripts); by naming
                           convention, *.local.* is not synced.
                           Needs separate review and probable rotation.
  sessions/, history.jsonl, caches, telemetry — ephemeral
  plugins/, marketplace skills and agents — reinstallable

The working copies at ~/.claude/skills/* and
~/.claude/projects/-Users-davidglidden/memory are symlinks into this
directory, so every write flows here automatically. install.sh
recreates the symlinks on a fresh machine.

FOLLOW-ON (flagged, not in this commit):
  settings.local.json contains a HuggingFace token and an SSH password
  as plaintext strings inside allowed Bash command patterns. These
  should be rotated and moved to secure storage (keychain / pass /
  env file outside the settings file).
