feat: change node ownership to namespace instead of creator

When a node is created in a namespace, the namespace now owns it rather than the creator. This allows namespaces to manage content ownership. Namespace nodes themselves remain owned by their creator. Users retain transitive ownership through their default namespace: user→has_ownership→namespace→has_ownership→node.

-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project
-
-Axolotl (`ax`) is a CLI-native issue tracker built in Go, using a local SQLite file (`.ax.db`) as its database. It's designed for use by individuals and AI agents, with JSON output support for machine integration.
-
-## Commands
-
-```bash
-go build -o ax .        # Build the binary
-go test ./...           # Run all tests (e2e_test.go covers most functionality)
-go test -run TestName . # Run a single test by name
-```
-
-## Architecture
-
-The codebase has three distinct layers:
-
-### 1. `cmd/` — CLI layer (Cobra)
-Parses flags into typed input structs and calls the service layer. `root.go` handles alias expansion (including `$me`, `$@`, `$1`-`$N` variable substitution) and wires up the `NodeService`. Also contains `output.go` for colored terminal output and JSON serialization.
-
-### 2. `service/` — Business logic
-`NodeService` is the central interface (`service/node_service.go`). The implementation (`node_service_impl.go`) enforces:
-- Permission model via `getPermContext()` — BFS from the user's own node following permission rels
-- Blocker validation (can't close an issue with open blockers)
-- `@mention` extraction → automatic edge creation
-- Single-value relation enforcement (`assignee`, `in_namespace`)
-- Auto-creation of referenced user/namespace nodes
-
-### 3. `store/` — Persistence and configuration
-`GraphStore` interface wraps SQLite with graph primitives: nodes, tags, and typed directed edges. Schema is 3 tables (`nodes`, `tags`, `rels`). All multi-step ops use `store.Transaction()`. Also contains `Config` for user settings, aliases, and session management.
-
-## Core Data Model
-
-**Node**: a graph node with a 5-char ID, title, content, `Tags []string`, and `Relations map[string][]string`.
-
-**Property tags** use the `_key::value` pattern: `_type::issue|note|user|namespace`, `_status::open|done`, `_prio::high|medium|low`.
-
-**Relation types** (`models/rel_type.go`): `blocks`, `subtask`, `related`, `assignee` (single-value), `in_namespace` (single-value), `created`, `mentions`, `can_read`, `can_create_rel`, `can_write`, `has_ownership`.
-
-**Permission model**: Four inclusive levels (1–4). Transitive via BFS from user's self-owned node. `can_read`=1, `can_create_rel`=2, `can_write`=3, `has_ownership`=4. Creator auto-gets `has_ownership` on every new node. Users self-own. Deleting a node cascades to all nodes it owns. User/namespace nodes are globally readable.
-
-## Config
-
-The CLI searches upward from CWD for an `.ax` directory (like git), falling back to `~/.config/ax/` for config and `~/.local/share/ax/` for data. The `AX_USER` env var overrides the configured username. The database file `ax.db` is similarly discovered by walking upward.
