feat(mongodb): extend parser to support all mongosh commands#53
Conversation
Extend the MongoDB Shell parser grammar to recognize all mongosh commands with comprehensive test coverage. Grammar additions: - Collection methods: write operations, index/schema management - Database methods: createCollection, dropDatabase, stats, serverStatus, etc. - Cursor methods: batchSize, collation, hint, maxTimeMS, toArray, etc. - Bulk operations: initializeOrderedBulkOp, Bulk.find, Bulk.insert, etc. - Connection methods: Mongo(), connect(), getDB, setReadPref, etc. - Replication methods: rs.status, rs.initiate, rs.add, rs.reconfig, etc. - Sharding methods: sh.status, sh.enableSharding, sh.shardCollection, etc. - Encryption methods: KeyVault, ClientEncryption via db.getMongo() - Native shell functions: cat, load, quit, pwd, sleep, etc. - Query plan cache: db.collection.getPlanCache().list/clear/etc. - Atlas-specific: Search Index methods, Stream Processing (sp.*) - Object constructors: BinData, Binary, BSONRegExp, HexData Test files: 300+ test files covering all command categories Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Pull request overview
This PR extends the MongoDB Shell parser grammar to recognize all mongosh commands, transforming it from a basic parser to a comprehensive one supporting 300+ commands across 14 categories. The grammar is intentionally permissive to allow for future translator implementations.
Changes:
- Extended grammar to support 300+ mongosh commands across collection operations, cursor methods, database administration, bulk operations, connections, replication, sharding, encryption, and Atlas-specific features
- Added comprehensive test coverage with 306 test files organized by command category
- Regenerated parser files from updated ANTLR grammar
