Viktor Barzin 2825cb1703 workstation: per-user code_layout — workspace puts project repos under ~/code (ancamilea + tripit)
Viktor asked to restructure Anca's setup: her ~/code WAS the infra clone
itself; he wants ~/code to be the directory where all her project repos
(tripit etc.) live side by side, with infra moved to a subdirectory.

- roster.yaml gains per-user 'code_layout: single|workspace' + 'repos',
  validated + derived by roster_engine.py (12 new tests, 40 total).
- t3-provision-users reconcile: auto-migrates a single-layout ~/code to
  ~/code/infra (running processes follow the moved inode), hoists nested
  project clones to the workspace root, clones roster repos from Forgejo
  AS the user (their PAT makes private repos work), and wires the
  documented forgejo remote + forgejo/master upstream into clones that
  predate that contract.
- Fixed a latent TSV bug: empty jq @tsv fields collapse under tab-IFS
  read, shifting later fields left (groups was only safe by being the
  last field) — emit '-' sentinels instead.
- start-claude.sh session freshen is layout-aware (freshens each repo
  under ~/code for workspace users).
- managed claudeMd + AGENTS.md non-admin recipe + multi-tenancy.md
  updated in the same change.

Applied live: ancamilea = workspace (infra at ~/code/infra, her existing
tripit clone hoisted to ~/code/tripit, master upstream switched to
forgejo/master); emo stays single layout, untouched. [ci skip]

# `useradd -m`. Existing users are repointed to this during their migration.
