feat: v1.11.0 PostgreSQL compatibility and SQL feature expansion (#2090)

* Add structured audit logging with immutable audit trail

Introduces a new --audit-log flag that records all gRPC operations as
structured JSON events in immudb's tamper-proof KV store. Events are
stored under the audit: key prefix in systemdb, queryable via Scan and
verifiable via VerifiableGet. An async buffered writer ensures minimal
latency impact. Configurable event filtering (all/write/admin) via
--audit-log-events flag.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Add PostgreSQL ORM compatibility layer and verification functions

Extend the pgsql wire protocol with immudb verification functions
(immudb_state, immudb_verify_row, immudb_verify_tx, immudb_history,
immudb_tx) accessible via standard SQL SELECT statements.

Add pg_catalog resolvers (pg_attribute, pg_index, pg_constraint,
pg_type, pg_settings, pg_description) and information_schema
resolvers (tables, columns, schemata, key_column_usage) to support
ORM introspection from Django, SQLAlchemy, GORM, and ActiveRecord.

Add PostgreSQL compatibility functions: current_database,
current_schema, current_user, format_type, pg_encoding_to_char,
pg_get_expr, pg_get_constraintdef, obj_description, col_description,
has_table_privilege, has_schema_privilege, and others.

Add SHOW statement emulation for common ORM config queries and
schema-qualified name stripping for information_schema and public
schema references.

* Implement EXISTS and IN subquery support in SQL engine

Replace the previously stubbed ExistsBoolExp and InSubQueryExp
implementations with working non-correlated subquery execution.

EXISTS subqueries resolve the inner SELECT and check if any rows
are returned. IN subqueries resolve the inner SELECT, iterate the
result set, and compare each value against the outer expression.
Both support NOT variants (NOT EXISTS, NOT IN).

Correlated subqueries (referencing outer query columns) ar... (continued)
