refactor: clean CLI taxonomy — canonical subcommands, merged memory.update, no aliases

- calendar: split write → create/read/update/delete/share
- contacts: rename lookup → read
- memory: merge write+forget → update (unified action field in operations)
- Remove all alias/normalization logic from adapter and handlers
- Update tool_postprocessor ui_hints builders to canonical keys
- Remove frontend legacy TOOL_CALL_START/ARGS/END events and ToolCallItem
- Update SKILL.md files and protocol docs
- Update tests and settings screens
