When OPENCLAW_STATE_DIR changes between session creation and resolution
(e.g., after reinstall or config change), absolute session file paths
pointing to other agents' sessions directories were rejected even though
they structurally match the valid .../agents/<agentId>/sessions/... pattern.
The existing fallback logic in resolvePathWithinSessionsDir extracts the
agent ID from the path and tries to resolve it via the current env's
state directory. When those directories differ, the containment check
fails. Now, if the path structurally matches the agent sessions pattern
(validated by extractAgentIdFromAbsoluteSessionPath), we accept it
directly as a final fallback.
