Subject: [PATCH] fix: pass --dir parameter from attach command to SDK client

The --dir parameter was being ignored in attach command, causing
sessions to use the client's current directory instead of the
specified path. Wire the parameter through TUI to SDK client.

Changes:
- Parse and resolve --dir argument in attach command
- Pass directory through TUI app to SDKProvider
- SDK client sends x-opencode-directory header to server

Fixes #5380
