server_sessions 0.1.0

Framework-agnostic session runtime (portable, from server_data/sessions).

Unreleased

• Aligned session configuration and contract dependencies with the current server runtime.
• Invalidated rotated or destroyed session IDs and bound signed/encrypted cookie payloads to their cookie names.
• Preserved filesystem sessions with non-expiring options and isolated cookie options between sessions.
• Remove the unused server_cache runtime dependency; cache-backed sessions continue to accept a server_contracts repository directly.

0.1.0

• Initial extraction from server_data/src/sessions (PR G)
