support partitioned table

Motivation

Support reading partitioned tables. Currently, partitioned table reading is completely blocked:

1. BinaryRow is a stub — cannot hold/parse actual partition data
2. No partition path generation code (e.g., dt=2024-01-01/hr=12)
3. TableScan discards partition info and builds wrong bucket paths
4. TableRead explicitly rejects partitioned tables with Unsupported error

Sub-tasks

• Implement BinaryRow deserialization to decode partition binary bytes #126 — Implement BinaryRow deserialization to decode partition binary bytes
• Implement partition path generation (PartitionPathUtils) #127 — Implement partition path generation (PartitionPathUtils)
• Support partitioned table in TableScan and TableRead #131 — Support partitioned table in TableScan and TableRead (+ integration tests)

Dependency Order

#126 (BinaryRow) ──→ #127 (PartitionPath) ──→ #131 (TableScan + TableRead + Tests)

#126 and #127 can be developed in parallel.

@luoyuxia I'd like to pick up #127 — it aligns well with the FileIO path handling improvements I'm working on in #106.
