Update C++ tsfile-cli command surface and data workflows

[SpriCoder]

Summary

• ls: lists model/object rows for current files; example: tsfile-cli ls -f csv data.tsfile
• schema: reports model,object,column,category,data_type,encoding,compression; example: tsfile-cli schema -t sensors -f csv data.tsfile
• meta: reports file summary fields; example: tsfile-cli meta data.tsfile
• stats: reports FIELD statistics with counts, null counts, time range, values, and source fields; example: tsfile-cli stats -t sensors -m temperature -f csv data.tsfile
• count: reports per-column counts without synthetic summary rows; example: tsfile-cli count -t sensors -f csv data.tsfile
• sketch: prints the physical file sketch; example: tsfile-cli sketch data.tsfile
• head: reads the first rows with offset/limit/filter support; example: tsfile-cli head -t sensors -m temperature -n 20 -f csv data.tsfile
• cat: streams all matching rows with the same row filters; example: tsfile-cli cat -t sensors --tag-filter site eq north -m temperature -f ndjson data.tsfile
• export: exports one object or multiple objects with numbered outputs and a manifest; example: tsfile-cli export -t sensors --type csv -o sensors.csv data.tsfile
• write: imports strict CSV into a new table-model TsFile with explicit --tag / --field declarations; example: printf 'time,site,temperature\n0,north,21.5\n1,north,21.7\n' | tsfile-cli write --table sensors --tag site STRING --field temperature DOUBLE --stdin -o sensors.tsfile
