Replace worktree-centric language with team-centric framing across
CLAUDE.md and skills. Agents now identify by $WORKTREE_TEAM env var
instead of resolving git internals. This prevents agents from
following .git pointers back to the main repo and crossing boundaries.
- CLAUDE.md: rename section to "Team boundaries", reference $WORKTREE_TEAM
- sprint-start: add TEAM BOUNDARY rule to agent spawn prompt
- sprint-plan: replace "worktree-relative paths" with "relative paths only"
- pr-review: replace "worktree" with "team directory", note cross-dir
reading is a main-team privilege only
