Make initdb cache creation atomic by copying into a same-parent temporary directory and publishing it with an atomic rename. Concurrent cold-cache writers now treat an existing final cache as success instead of exposing a partially-copied data directory.

Fix stop and restart ignoring configured shutdown mode and timeout — they were hardcoding ShutdownGraceful with a 30-second timeout instead of using the config values, causing with/withCached to block unnecessarily on shutdown

Change default shutdown mode to ShutdownFast (SIGINT) with a 5-second timeout, which is more appropriate for a testing library

Remove Hungarian-style field prefixes from all record types using NoFieldSelectors, DuplicateRecordFields, and OverloadedRecordDot
- Config: configPort → port, configDatabaseName → databaseName, etc.
- Database: dbPort → port, dbDataDirectory → dataDirectory, etc.
- PostgresProcess: postgresProcess → process, postgresPid → pid
- DumpOptions: dumpFormat → format, dumpCreateDb → createDb, etc.
- Snapshot: snapshotPath → path, snapshotTemporary → temporary
- CacheKey: cacheKeyPgVersion → pgVersion, cacheKeyConfigHash → configHash
- CacheConfig: cacheConfigRoot → root, cacheConfigCow → cow, cacheConfigEnabled → enabled
- Error types: all prefixed fields renamed similarly
Remove accessor functions from Database module (dataDirectory, socketDirectory, port, databaseName, user); use dot syntax instead (e.g., db.port)
Database is now exported with (..) from EphemeralPg for HasField resolution
Consumers should enable OverloadedRecordDot to access record fields
