fix(session-recovery): reorder error detection to prevent false tool_result_missing match

Anthropic's extended thinking error messages contain 'tool_use' and 'tool_result'
in the documentation URL text, causing incorrect detection as tool_result_missing
instead of thinking_block_order.

Fix: Check thinking_block_order BEFORE tool_result_missing.
