fix: remove machine-specific symlinks from repository

- Remove .claude and packages/web/agent-orchestrator.yaml symlinks
- Add them to .gitignore to prevent re-committing
- These are development convenience links created per-worktree

Fixes Bugbot comment about environment-dependent paths that break
on other machines.
