Change routing.mode default from "auto" to "" (empty/disabled).
This fixes GH#1165 where fresh `bd init --prefix X` followed by
`bd create` would unexpectedly route to ~/.beads-planning and fail
with "database not initialized: issue_prefix config is missing".
Auto-routing now requires explicit opt-in via:
- `bd init --contributor` flag, OR
- `bd config set routing.mode auto`
Includes test verifying the default and doc updates clarifying
the opt-in requirement.
Addresses the self-hosting recursion problem where contributors using
beads-the-tool on beads-the-project leak personal issues into PRs.
Design recommends auto-routing (Approach 4):
- Detect user role via git remote URL (SSH=maintainer, HTTPS=contributor)
- Route contributor issues to ~/.beads-planning automatically
- Zero-friction default with explicit override available
Key finding: bd-6x6g needs implementation - routing is calculated but
not actually used to switch target repo in bd create.
Enables bd-lfak (PR preflight checks) to implement pollution detection.
