        Returns time-series CPU, memory, and disk metrics for a capsule.
        Three tiers are available with different granularity and retention:
        - `10m`: 500ms samples, last 10 minutes
        - `2h`: 30-second averages, last 2 hours
        - `24h`: 5-minute averages, last 24 hours

        For running capsules, data comes from the host agent's in-memory
        ring buffer. For paused capsules, data is read from persisted
        snapshots in the database. Stopped/destroyed capsules return 404.

        The connection closes automatically after the process exits.

        Opens a WebSocket connection for an interactive PTY (terminal) session.
        Supports creating new sessions, sending input, resizing, killing, and
        reconnecting to existing sessions.

        **Client sends** (first message — start a new PTY):
        ```json
        {
          "type": "start",
          "cmd": "/bin/bash",
          "args": [],
          "cols": 80,
          "rows": 24,
          "envs": {"TERM": "xterm-256color"},
          "cwd": "/home/user",
          "user": "user"
        }
        ```
        All fields except `type` are optional. Defaults: cmd="/bin/bash", cols=80, rows=24.

        **Client sends** (first message — reconnect to existing PTY):
        ```json
        {"type": "connect", "tag": "pty-abc123de"}
        ```

        **Client sends** (after session is established):
        ```json
        {"type": "input", "data": "<base64-encoded bytes>"}
        {"type": "resize", "cols": 120, "rows": 40}
        {"type": "kill"}
        ```

        **Server sends**:
        ```json
        {"type": "started", "tag": "pty-abc123de", "pid": 42}
        {"type": "output", "data": "<base64-encoded PTY bytes>"}
        {"type": "exit", "exit_code": 0}
        {"type": "error", "data": "description", "fatal": true}
        {"type": "ping"}
        ```

        PTY data (input and output) is base64-encoded because it contains raw
        terminal bytes (escape sequences, control codes) that are not valid UTF-8.

        Sessions persist across WebSocket disconnections — the process keeps
        running in the capsule. Use the `tag` from the "started" response to
        reconnect later.
