improvement(tables): raise the max column limit to 1000

[TheodoreSpeaks]

Summary

• Raise TABLE_LIMITS.MAX_COLUMNS_PER_TABLE from 50 to 1000
• Every enforcement site already derives from this constant — schema validation, single add-column, bulk column additions, workflow output columns, and the boundary contract — so no other change is needed
• Row size is still bounded independently by MAX_ROW_SIZE_BYTES (400KB) and queries by MAX_QUERY_RESULT_BYTES; rows are stored as jsonb with no per-column index, so wider schemas add no DDL cost

Type of Change

• Improvement

Testing

• apps/sim/lib/table/__tests__/validation.test.ts — 68 passed (the max-columns case derives its fixture from the constant)
• bun run lint clean (9 pre-existing warnings in zoho-desk.test.ts, untouched here)
• Full audit suite passed: check:boundaries, check:api-validation:strict, check:utils, check:zustand-v5, check:react-query, check:client-boundary, check:bare-icons, check:icon-paths, check:realtime-prune, skills:check, agent-stream-docs:check

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

PR Summary

Low Risk
Single numeric limit change with no auth or data-model changes; remaining row and query byte limits still constrain wide schemas.

Overview
Raises TABLE_LIMITS.MAX_COLUMNS_PER_TABLE from 50 to 1000 in constants.ts.

Schema validation, API contracts (createTableBodySchema), add-column and bulk column paths, and related tests all read this constant, so the new cap applies everywhere without further edits. Row size (MAX_ROW_SIZE_BYTES) and query result size limits still bound payload size independently; rows stay jsonb without per-column DDL.

Greptile Summary

This PR raises the shared maximum number of columns per table from 50 to 1000.

• Updates the central table-limit constant used by existing validation and column-creation paths.
• Leaves the independent row-size and query-result limits unchanged.

Confidence Score: 5/5

The PR appears safe to merge, with the previously acknowledged wide-grid performance concern remaining non-blocking.

No blocking failure remains.
