MAESTRO: Fix ssh-remote-execution.md documentation inaccuracies

- Corrected Per-Agent Configuration to Per-Session Configuration
  (SSH is session-level only, not per-agent with global defaults)
- Fixed dropdown options from incorrect "Use Global Default"/"Force
  Local" to actual "Local Execution"/[Remote Name] options
- Removed incorrect "Resolution Order" section (5-level priority
  algorithm doesn't exist in source code)
- Clarified global default is a visual indicator, not automatic
- Removed incorrect PTY limitation claim (PTY IS available via
  RequestTTY: 'force' and -tt flags)
- Updated Limitations section with accurate shell initialization info
- Changed hyphens to em-dashes for consistency

-| **Use Global Default** | Follows the global setting (shows which remote if one is set) |
-| **Force Local Execution** | Always runs locally, ignoring any global default |
-| **[Specific Remote]** | Always uses this remote, regardless of global setting |

-When spawning an agent, Maestro resolves which SSH remote to use:
+SSH remote execution is configured at the **session level**:
 
-1. **Per-agent explicit remote** → Uses that specific remote
-2. **Per-agent "Force Local"** → Runs locally (ignores global)
-3. **Per-agent "Use Global Default"** → Falls through to global setting
-4. **Global default set** → Uses the global default remote
-5. **No global default** → Runs locally
+- When you create a new session, you choose whether it runs locally or on a specific remote

 ### Tips
 
-- **Import from SSH config**: Use the dropdown when adding remotes to import from `~/.ssh/config`—saves time and keeps configuration consistent
-- **Bastion hosts**: Use `ProxyJump` in your SSH config for multi-hop connections; Maestro inherits this automatically
-- **Key management**: Use `ssh-agent` to avoid passphrase prompts
-- **Keep-alive**: Configure `ServerAliveInterval` in SSH config for long sessions
-- **Test manually first**: Verify `ssh host 'claude --version'` works before configuring in Maestro
