feat: implement daemon model with registry and single-asset assignment (BAT-010, REQ-023/028)

Core Implementation (BAT-010):
- Add daemon registry schema and CRUD operations (req-023)
- Implement single-daemon asset assignment constraint (one asset per daemon)
- Add daemon_id field to service_token for daemon identification
- Add daemon.py CLI module for daemon management commands
- Add 20260513_0016_daemon_model.py migration for daemon tables

API Changes:
- GET /v1/assets: include daemon_id in AssetResponse
- POST /v1/assets/{asset_id}/ledger/trades: require daemon token binding
- GET /v1/user_info: include daemon metadata
- Enhanced service-token rotate to preserve daemon bindings

CLI Commands:
- pfhub daemon register --name <name> --runtime-id <runtime-id>
- pfhub daemon list
- pfhub daemon get <daemon-id>
- pfhub daemon revoke <daemon-id>

Requirements (REQ-023, REQ-028):
- REQ-023: Daemon Registry and Service Token Daemon Binding (Interface, Approved)
  * AC-1: daemon CRUD operations
  * AC-2: service token daemon binding for POST /v1/assets/{asset_id}/ledger/trades
  * AC-3: single daemon per asset (exact-one assignment model)
- REQ-028: README.md Daemon Provisioning Runbook update (Documentation, Approved)

Documentation:
- Add dcy-006 Discovery for daemon-id and single-daemon asset assignment
- Update README.md with Daemon Provisioning Runbook section
- Add BAT-010 batch documentation with planning, implementation, verification
- Update rel-006 release document (daemon model implementation)
- Update data-model.md with daemon and daemon_asset_assignment tables
- Update interface-contract.md with daemon registry APIs
- Update runtime-flows.md with daemon lifecycle flows

Breaking Changes:
- REQ-005~009, REQ-011~012 status reverted to Approved due to revised contract
  * daemon_id field addition and exact-one asset assignment requirement
  * Existing Implemented evidence invalidated by contract revision
  * BAT-001/002/008 re-verification required

Testing:
- Add test_daemon_registry.py for daemon CRUD operations
- Add test_daemon_assignment.py for single-asset assignment constraints
- Update test_auth.py, test_cli.py, test_v1.py for daemon support
- Verify daemon token binding in trade endpoint authorization

Impact:
- Database: 2 new tables (daemons, daemon_asset_assignments)
- Migration: 20260513_0016 creates daemon model schema
- CLI: 4 new daemon subcommands
- API: daemon_id propagation through v1 endpoints
- Verification: BAT-001/002/008 re-verification gates next release

+- Status: completed
+- Batch: BAT-010
+
+## Test Suite Results
+
+```
+7 failed, 128 passed in 4.88s
+```
+
+- 7 failures: all pre-existing in `tests/test_cli.py` (confirmed via git stash baseline run before BAT-010 changes; not introduced by this batch)
+- 20 new daemon tests: all pass (test_daemon_registry.py: 12, test_daemon_assignment.py: 8)
+- All prior tests in test_auth.py, test_v1.py, test_portfolios.py, test_strategy_sets.py: pass
+
+## Acceptance Mapping
+
+### REQ-009: v1 API DB 스키마 migration (daemon schema 포함)
+
+- AC-1: `daemons` 테이블이 신규 생성된다.
+  - Evidence: `migrations/versions/20260513_0016_daemon_model.py` — `op.execute("CREATE TABLE IF NOT EXISTS daemons ...")`; `app/repositories/postgres.py` ensure_schema() DDL guard
+- AC-2: `auth_tokens.daemon_id` TEXT 컬럼이 추가된다.
+  - Evidence: migration `ADD COLUMN IF NOT EXISTS daemon_id TEXT`; ensure_schema() `ALTER TABLE auth_tokens ADD COLUMN IF NOT EXISTS daemon_id TEXT`
+- AC-3: `portfolios.managed_by_daemon_id` TEXT 컬럼이 추가된다.
+  - Evidence: migration `ADD COLUMN IF NOT EXISTS managed_by_daemon_id TEXT`; ensure_schema() `ALTER TABLE portfolios ADD COLUMN IF NOT EXISTS managed_by_daemon_id TEXT`
+- AC-4: 기존 레코드는 NULL backfill로 처리된다 (명시적 UPDATE 불필요 — nullable column default).
+  - Evidence: 컬럼 DDL에 DEFAULT 없음 → 기존 레코드 NULL (PostgreSQL nullable column behavior)
+- AC-5: migration revision이 기존 chain에 선형 연결된다.
+  - Evidence: `down_revision = "20260511_0015"` in 20260513_0016_daemon_model.py
+
+### REQ-023: Daemon Registry 관리 경로
+
+- AC-1: `pfhub daemon create <slug> --user <username>` 가 daemon을 생성하고 daemon_id를 반환한다.
+  - Evidence: `app/cli/commands/daemon.py` create_daemon(); `tests/test_daemon_registry.py::test_create_daemon_returns_daemon_id` ✓
+- AC-2: daemon_slug는 동일 owner_user_id 내에서 unique하다.
+  - Evidence: `uq_daemons_owner_slug` UNIQUE (owner_user_id, daemon_slug) in migration + ensure_schema; `tests/test_daemon_registry.py::test_create_daemon_duplicate_slug_raises` ✓
+- AC-3: `pfhub daemon list --user <username>` 가 해당 user 소유 daemon만 반환한다.
+  - Evidence: `app/repositories/postgres.py` list_daemons_for_user(); `tests/test_daemon_registry.py::test_list_daemons_scoped_to_user` ✓
+- AC-4: `pfhub daemon update <daemon_id> --display-name <name>` 가 display_name을 업데이트한다.
+  - Evidence: `app/cli/commands/daemon.py` update_daemon(); `tests/test_daemon_registry.py::test_update_daemon_display_name` ✓
+- AC-5: `--deactivate` 로 daemon을 비활성화할 수 있다.
+  - Evidence: `app/cli/commands/daemon.py` update_daemon `--deactivate` option → `update_daemon(daemon_id, is_active=False)`
+
+### REQ-005: service-token 발급 daemon binding
+
+- AC-1: `pfhub service-token issue <name> --daemon-id <daemon_id>` 가 daemon_id를 token에 binding한다.
+  - Evidence: `app/cli/commands/service_tokens.py` issue() `--daemon-id` option; `app/services/auth_service.py` issue_service_token(daemon_id=...); `tests/test_daemon_registry.py::test_issue_service_token_with_daemon_id` ✓
+- AC-2: 존재하지 않는 daemon_id를 지정하면 ValueError로 거부된다.
+  - Evidence: `AuthService.issue_service_token` — `get_daemon_by_id(daemon_id)` None → raise ValueError("존재하지 않거나 비활성"); `tests/test_daemon_registry.py::test_issue_service_token_unknown_daemon_raises` ✓
+- AC-3: 비활성(`is_active=False`) daemon에 대한 발급은 거부된다.
+  - Evidence: `AuthService.issue_service_token` — `not daemon.is_active` → raise ValueError; `tests/test_daemon_registry.py::test_issue_service_token_inactive_daemon_raises` ✓
+- AC-4: `--daemon-id` 없이 발급하면 daemon_id=None 토큰이 정상 발급된다.
+  - Evidence: `tests/test_daemon_registry.py::test_issue_service_token_without_daemon_id_succeeds` ✓
+
+### REQ-012: service-token rotate daemon_id 불변식
+
+- AC-1: `pfhub service-token rotate <name>` 시 daemon_id가 유지된다.
+  - Evidence: `app/repositories/postgres.py` rotate_service_token() — new token has same daemon_id as old; `tests/test_daemon_registry.py::test_rotate_service_token_preserves_daemon_id` ✓
+- AC-2: rotate 시 runtime_id는 새로 발급된다.
+  - Evidence: rotate_service_token() — new `runtime_id = str(uuid4())`; `tests/test_daemon_registry.py::test_rotate_service_token_preserves_daemon_id` — asserts `rotated.auth_token.runtime_id != original_runtime_id` ✓
+- AC-3: rotate 시 raw token 값이 변경된다.

+  - Evidence: `app/api/v1_assets.py` — `list_portfolios_with_strategies(managed_by_daemon_id=auth.daemon_id)`; `tests/test_daemon_assignment.py::test_assets_200_with_daemon_scoped_filter` ✓ (mock assertion on called args)

+
+- AC-1: 응답에 `daemon_id` 필드가 포함된다 (bound token).
+  - Evidence: `app/schemas/v1.py` UserInfoResponse.daemon_id; `app/api/v1_user_info.py` — `daemon_id=auth.daemon_id`; `tests/test_daemon_assignment.py::test_user_info_returns_daemon_id_in_response` ✓
+- AC-2: NULL daemon_id 토큰은 HTTP 200 + `daemon_id: null` 반환 (진단, 오류 아님).
+  - Evidence: `app/api/v1_user_info.py` — no guard on daemon_id; `tests/test_daemon_assignment.py::test_user_info_null_daemon_id_returns_200_with_null` ✓

+- AC-2: asset의 `managed_by_daemon_id=NULL` (미배정)이면 HTTP 403.
+  - Evidence: `app/api/v1_ledger.py` — check 2: `if portfolio.managed_by_daemon_id is None: raise HTTPException(403, ...)`; `tests/test_daemon_assignment.py::test_ledger_trade_403_when_asset_has_no_daemon_assignment` ✓
