Config refactor: DewConfig.raw + per-package extensions (DEW-0007)

DewConfig in core is now a thin YamlMap wrapper. Feature-specific config
classes live in their own packages and expose themselves via Dart extensions:

- KanbanConfig, ColumnConfig, TicketTypeConfig + KanbanDewConfig extension
  moved to packages/kanban/lib/src/kanban_config.dart
- McpConfig + McpDewConfig extension added to
  packages/mcp/lib/src/mcp_config.dart
- DewConfig.fromYaml() now trivially wraps the raw YamlMap
- All call sites unchanged: context.config.kanban.* / context.config.mcp.*
- Added yaml dependency to dew_mcp pubspec
- Updated core test to validate raw yaml instead of typed fields
- Fixed cross-suite Directory.current isolation (existing issue, not introduced)

 Add `dew init [path]` command. Core defines DewInitHook interface with onInit(root, options). Options include bool gitkeep (default true). Each package registers a hook. Kanban hook creates: column dirs (from config), archive/, attachments/ under .project/kanban/. --[no-]gitkeep flag adds .gitkeep to empty dirs. Must run after storage refactor so dir structure matches new layout.

 DewConfig in core becomes a thin wrapper: `class DewConfig { final YamlMap raw; }`. Each package adds a Dart extension with a typed getter (e.g. KanbanDewConfig, McpDewConfig). KanbanConfig/ColumnConfig/TicketTypeConfig move to dew_kanban; McpConfig moves to dew_mcp. Call sites unchanged: context.config.kanban.prefix etc.

 Move ticket .md files from flat .project/kanban/ into column subdirectories (.project/kanban/todo/DEW-0001.md). Attachments live at .project/kanban/attachments/<ticket-id>/ (stable path, unaffected by moves). TicketStore changes: _filePath needs column, findById searches all column dirs, move physically moves the .md file, delete removes .md + attachments/<id>/ if present, create writes into correct column dir.
