v0.28.0

Summary

v0.28.0 brings type-based ANSI styling for query results, fuzzy completion improvements, and a large internal architecture overhaul that simplifies the codebase significantly.

Highlights

• CLI_TYPE_STYLES system variable: Configure per-type ANSI colors for query results using a colon-separated TYPE=STYLE format (e.g., SET CLI_TYPE_STYLES = 'STRING=green:INT64=cyan:NULL=dim'). Supports named colors, attributes, raw SGR numbers, 256-color, and truecolor. See docs/system_variables.md for full reference.
• SQL statement skeletons in fuzzy finder: Fuzzy completion now includes SQL statement templates for faster query authoring.
• Format system rewrite: New Cell interface with PlainCell/StyledCell, format registry, and unified table rendering. Migrated from go-runewidth to go-tabwrap.
• Architecture simplifications: Extracted TransactionManager, restructured system variables into nested groups, migrated to named capture groups, simplified SQL execution pipeline. Net reduction in code complexity.
• spanemuboost v0.3.4: Adopted LazyEmulator for deferred emulator startup in tests and TestMain helper for cleaner test infrastructure.
