Enhance CLI documentation and functionality for session resumption

- Updated README and CLI documentation to include new commands for resuming sessions: `--continue` for the most recent session and `--resume <id>` for specific sessions.
- Added examples in the CLI help output and detailed instructions on resuming sessions in the documentation.
- Improved user experience by automatically displaying the resume command upon exiting a session.

+### Resuming Sessions
+
+When you exit a CLI session, a resume command is printed:
+
+```
+Resume this session with:
+  hermes --resume 20260225_143052_a1b2c3
+
+Session:        20260225_143052_a1b2c3
+Duration:       12m 34s
+Messages:       28 (5 user, 18 tool calls)
+```
+
+To resume:
+
+```bash
+hermes --continue                          # Resume the most recent CLI session
+hermes -c                                  # Short form
+hermes --resume 20260225_143052_a1b2c3     # Resume a specific session by ID
+hermes -r 20260225_143052_a1b2c3           # Short form
+hermes chat --resume 20260225_143052_a1b2c3  # Explicit subcommand form
+```
+
+Resuming restores the full conversation history from SQLite (`~/.hermes/state.db`). The agent sees all previous messages, tool calls, and responses — just as if you never left. New messages append to the same session in the database.
+
+Use `hermes sessions list` to browse past sessions and find IDs.
