Phase 5 — ERP Features: - CREATE VIEW name AS SELECT ... — parser + executor with view expansion - DROP VIEW — parser + executor - CREATE MIGRATION name AS 'sql' — parser + executor, stored in LSM-Tree - APPLY MIGRATION name — parser + executor, replays stored migration SQL - Views table in ExecutionContext, expanded on SELECT FROM view Phase 6 — Production Readiness: - Deadlock detection: timeout-based auto-abort for stale transactions (30s default) - TxnManager.txnTimeoutMs configurable - Structured JSON logging module (logging.nim) with levels: debug/info/warn/error - Admin dashboard Web UI at GET /admin — SQL playground, schema browser, metrics - Dark theme HTML/CSS with tabs Lexer: added tkView, tkMigration, tkApply tokens Parser: parseCreateView, parseDropView, parseCreateMigration, parseApplyMigration AST: nkCreateView, nkDropView, nkCreateMigration, nkApplyMigration nodes All 216 tests pass
