Feature Description

Add a "Clone" action to the session actions menu that allows users to duplicate an existing chat session with all its messages, tool calls, and configuration.

Requirements

Add "Clone" button to the session actions menu (SessionItemActionsDropdown)
Show a dialog allowing the user to customize the cloned session name
Default name should be "{original name} (Copy)"
Create a new session with:
- New ID
- Same messages (with new IDs, preserving thread structure)
- Same tool calls (with new IDs, mapped to new message IDs)
- Same owner
- Same current leaf message (mapped to new ID)
- Same configured tools
- Same LLM model
- Same settings
- Same group assignment
- Preserved timestamps (createdAt/updatedAt from original messages)

Implementation Steps

1. Add Clone Dialog UI

Create SessionListDialogState.CloneSession variant in SessionListViewModel
Add showCloneSessionDialog(session) and updateDialogCloneName(name) functions
Include fields: sessionId, defaultName, nameInput, onNameInputChange, onCloneConfirm, onDismiss

2. Add Clone Action to UI Layers

Insert "Clone" menu item in SessionItemActionsDropdown (SessionListItem.kt)
Add onClone to DialogActions interface
Add onShowCloneSessionDialog to SessionListActions interface
Wire through to ViewModel
Create dialog composable in Dialogs.kt

3. Implement ViewModel Clone Logic

Add private cloneSession(sessionId, newName) function in SessionListViewModel
Call sessionRepository.cloneSession
Handle errors via notificationService
Select the new session on success
Close dialog

4. Add Repository and API Methods

Add suspend fun cloneSession(sessionId: Long, request: CloneSessionRequest): Either<RepositoryError, ChatSession> to SessionRepository
Create CloneSessionRequest(name: String) data class in common/models/api/core
Add Clone nested resource in SessionResource.kt
Implement API client method

5. Implement Server Endpoint and Service

Add POST route for SessionResource.ById.Clone in session routes
Create CloneSessionError sealed interface (SessionNotFound, InvalidName)
Add suspend fun cloneSession(id: Long, userId: Long, name: String): Either<CloneSessionError, ChatSession> to SessionService
Implement in SessionServiceImpl with authorization check

6. Implement Service-Level Cloning Logic

In SessionServiceImpl.cloneSession:

Validate name is not blank
Verify user owns original session (via SessionOwnershipDao.getOwner)
Load original session (sessionDao.getSessionById)
Create new session with same config (sessionDao.insertSession)
Set owner (sessionOwnershipDao.setOwner)
Load and clone messages (messageDao.getMessagesBySessionId + repeated insertMessage)
- Build oldId→newId mapping
- Preserve parent/child relationships
- Preserve original timestamps
Update new session's currentLeafMessageId to mapped value
Clone tool calls (toolCallDao.getToolCallsBySessionId + repeated inserts)
- Use mapped message IDs
- Preserve original status
Copy tool configs (sessionToolConfigDao.getEnabledToolsForSession + setToolsEnabledForSession)
All operations in single transaction for atomicity

Technical Notes

Use existing DAO methods (no batch insert methods for now)
Entire clone operation must be in a single transaction
Authorization check: verify user owns original session before cloning
Foreign key constraints ensure group ID validity
Message timestamps should be preserved from original
