docs(aphoria): update CLI reference with bulk import features

Add documentation for:
- --template flag (generate example TOML)
- --validate-only flag (check without importing)
- --format flag (table|json output)
- Validation details (what gets checked)
- Link to comprehensive bulk import guide

All examples tested and working.

 **Options:**
+- `--template` - Generate example TOML template (omit FILE to use this)
+- `--validate-only` - Check file format without importing
+- `--format <FORMAT>` - Output format: `table` (default, human-readable) or `json` (tooling integration)
 - `--authority-tier <TIER>` - Override authority tier for all imported claims (team_policy, expert, etc.)
 - `--source-guide <NAME>` - Track the guideline name for compliance filtering (stored in `.aphoria/ingested_guides.toml`)
 - `--dry-run` - Preview changes without writing to file
 - `--merge <STRATEGY>` - Merge strategy: `skip_existing` (default), `overwrite`, `fail_on_duplicate`
 
+**Validation:**
+
+Pre-import validation catches errors before any writes:
+- Invalid claim IDs (must be kebab-case: lowercase, hyphens only)
+- Unknown authority tiers
+- Empty required fields (provenance, invariant, consequence, category, created_by)
+- Duplicate IDs within import file
+- Duplicate concept_path+predicate combinations (warnings)
+
+All errors are reported at once with clear context (claim index, ID, field, error message).
+
+**See also:** [Bulk Import Guide](guides/bulk-claim-import.md) for complete documentation and examples.

 **TOML Format:**
