* Improve CLAUDE.md instructions and compact DB schema summary
- Add code validation instructions (cargo check, npm run check) to all
CLAUDE.md files with guidance to use only relevant feature flags
- Reference backend/CLAUDE.md and frontend/CLAUDE.md paths from root
- Add database querying guidance (psql commands for exact table info)
- Compact summarize_schema.py output: inline columns, shorten types,
one-line enums, drop indexes (use psql \d for exact info)
- Fix FK parsing for multi-line ALTER TABLE statements
- Result: schema summary reduced from 1514 lines/40KB to 194 lines/23KB
* cleaning
* fix: use prefix-based type abbreviations and filter CONSTRAINT pseudo-columns
- Change TYPE_ABBREVIATIONS matching from exact to prefix-based so
parametrized types (character(64) -> char(64)) and array types
(integer[] -> int[], real[] -> float[]) are properly abbreviated
- Skip CONSTRAINT lines inside CREATE TABLE blocks that were being
incorrectly matched as columns by the column regex
- Update summarized_schema.txt to reflect both changes
