fix(routing): auto-enable hydration and flush JSONL after routed create (#1251)

* fix(routing): auto-enable hydration and flush JSONL after routed create

Fixes split-brain bug where issues routed to different repos (via routing.mode=auto)
weren't visible in bd list because JSONL wasn't updated and hydration wasn't configured.

**Problem**: When routing.mode=auto routes issues to a separate repo (e.g., ~/.beads-planning),
those issues don't appear in 'bd list' because:
1. Target repo's JSONL isn't flushed after create
2. Multi-repo hydration (repos.additional) not configured automatically
3. No doctor warnings about the misconfiguration

**Changes**:

1. **Auto-flush JSONL after routed create** (cmd/bd/create.go)
   - After routing issue to target repo, immediately flush to JSONL
   - Tries target daemon's export RPC first (if daemon running)
   - Falls back to direct JSONL export if no daemon
   - Ensures hydration can read the new issue immediately

2. **Enable hydration in bd init --contributor** (cmd/bd/init_contributor.go)
   - Wizard now automatically adds planning repo to repos.additional
   - Users no longer need to manually run 'bd repo add'
   - Routed issues appear in bd list immediately after setup

3. **Add doctor check for hydrated repo daemons** (cmd/bd/doctor/daemon.go)
   - New CheckHydratedRepoDaemons() warns if daemons not running
   - Without daemons, JSONL becomes stale and hydration breaks
   - Suggests: cd <repo> && bd daemon start --local

4. **Add doctor check for routing+hydration mismatch** (cmd/bd/doctor/config_values.go)
   - Validates routing targets are in repos.additional
   - Catches split-brain configuration before users encounter it
   - Suggests: bd repo add <routing-target>

**Testing**: Builds successfully. Unit/integration tests pending.

* test(routing): add comprehensive tests for routing fixes

Add unit tests for all 4 routing/hydration fixes:

1. **create_routing_flush_test.go** - Test JSONL flush after routing
   - TestFlushRoutedRepo_DirectExport: Verify direct JSONL export
   - TestPerformAtomicExport: Test atomic file operations
   - TestFlushRoutedRepo_PathExpansion: Test path handling
   - TestRoutingWithHydrationIntegration: E2E routing+hydration test

2. **daemon_test.go** - Test hydrated repo daemon check
   - TestCheckHydratedRepoDaemons: Test with/without daemons running
   - Covers no repos, daemons running, daemons missing scenarios

3. **config_values_test.go** - Test routing+hydration validation
   - Test routing without hydration (should warn)
   - Test routing with correct hydration (should pass)
   - Test routing target not in hydration list (should warn)
   - Test maintainer="." edge case (should pass)

All tests follow existing patterns and use t.TempDir() for isolation.

* fix(tests): fix test failures and refine routing validation logic

Fixes test failures and improves validation accuracy:

1. **Fix routing+hydration validation** (config_values.go)
   - Exclude "." from hasRoutingTargets check (current repo doesn't need hydration)
   - Prevents false warnings when maintainer="." or contributor="."

2. **Fix test ID generation** (create_routing_flush_test.go)
   - Use auto-generated IDs instead of hard-coded "beads-test1"
   - Respects test store prefix configuration (test-)
   - Fixed json.NewDecoder usage (file handle, not os.Open result)

3. **Fix config validation tests** (config_values_test.go)
   - Create actual directories for routing paths to pass path validation
   - Tests now verify both routing+hydration AND path existence checks

4. **Fix daemon test expectations** (daemon_test.go)
   - When database unavailable, check returns "No additional repos" not error
   - This is correct behavior (graceful degradation)

All tests now pass:
- TestFlushRoutedRepo* (3 tests)
- TestPerformAtomicExport
- TestCheckHydratedRepoDaemons (3 subtests)
- TestCheckConfigValues routing tests (5 subtests)

* docs: clarify when git config beads.role maintainer is needed

Clarify that maintainer role config is only needed in edge case:
- Using GitHub HTTPS URL without credentials
- But you have write access (are a maintainer)

In most cases, beads auto-detects correctly via:
- SSH URLs (git@github.com:owner/repo.git)
- HTTPS with credentials

This prevents confusion - users with SSH or credential-based HTTPS
don't need to manually configure their role.
