feat(chat): align command, shell, and subtask UX (#444)

* feat: reload interface after skills operations

- Adds configurable delay before interface reload after skills changes
- Introduces polling to wait for application health after reload
- Updates UI to show reload message when installing or modifying skills

* feat: distinguish skills from commands in UI

- Displays skill badge for commands that are registered skills
- Prevents editing skills through command management interface
- Triggers interface reload after skill operations to reflect changes

* feat(chat): align command and subtask UX with opencode parity

Route commands/shell via parity paths, render delegated subtasks cleanly, and surface child-session permission/question prompts in parent chat.

* fix(ProjectEditDialog): improve layout consistency

* fix: update task icon and session handling in ToolPart

* feat(chat): add shell-mode input and collapse shell bridge output

Switch leading ! to shell mode UX and fold synthetic shell bridge assistant messages into the user shell bubble with inline output actions.

* fix: remove AI agent icon from file mention autocomplete

* fix: remove unused icon import from file mention component
