Added

• Add FstReader for loading FST waveform files through the same reader APIs as VCD and FSDB.
• Add Channel-based FIFO consumption to Pattern.wait() for ordered request/response pairing and per-ID routing.
• Add relative time access helpers for waveform analysis.
• Add Chinese README documentation.

Changed

• Refactor the pattern API around tick, channel, capture mode, and require semantics.
• Improve VCD reader error reporting for empty value-change data and unsupported sub-range access.

Fixed

• Restrict pattern trigger optimization to wait() steps.
