Temporal Context & Datetime Resolution

5 tools for temporal orientation and datetime computation. All tools execute locally within the compiled MCP server binary — no external API calls, no network access at runtime, no credential files. The binary is installed once via npm (or built from source with Docker) and all subsequent executions are fully offline. No OAuth or credentials required. Timezone and week-start preferences are stored in `config.json`. Unset fields default to system timezone and Monday week-start.
