Session creation now requires cwd= parameter (no fallback to daemon cwd).
Agent cwd is read-only — agents inherit from session, cannot override.
Frontends updated:
- NewSessionDialog: added Directory field with Browse button
- NewAgentDialog: removed Directory field
- createAgent(): removed cwd parameter
- Kate plugin: passes cwd when creating kate session
- Dolphin: removed cwd from agent/new call
Message history sanitization (backend.SanitizeMessages):
- Removes dangling tool calls (assistant with ToolCalls but missing results)
- Removes orphan tool results (tool message without preceding call)
- Applied before sub-agent context inheritance
- Applied before session persistence save
- Applied after compaction (defensive)
Includes unit tests for all sanitization cases.
