fix(sql-pglite): support parameterless SQL scripts

[k70suK3-k06a7ash1]

Parameterless SQL scripts currently fail through the PGlite row-query interface with cannot insert multiple commands into a prepared statement (SQLSTATE 42601). For example:

yield* sql`
  CREATE TABLE example (id INTEGER, value TEXT);
  CREATE INDEX example_id ON example (id);
  CREATE INDEX example_value ON example (value);
`

The adapter always calls PGlite's single-statement query API. This change separates execution into an internal Script | Parameterized tagged union: parameterless SQL uses exec, while statements with a non-empty parameter array keep using query with bound values. SQL is passed intact, including semicolons inside literals, comments and dollar-quoted blocks.

Scripts return the final statement's rows, or an empty array when there are no rows. This applies to ordinary row queries, .unprepared and .stream, preserving result-name transformations and SQL error classification. The .raw, .values and .valuesUnprepared paths retain their existing single-statement behavior.

This was originally encountered with the combined index creation in SqlMessageStorage on 4.0.0-rc.112. Current main already executes those indexes separately; the regression tests here reproduce the remaining adapter limitation directly.

Validation:

• Before the fix, the new regression file had 7 failures and 1 pass, reproducing SQLSTATE 42601.
• pnpm test --run packages/sql/pglite/test: 7 files, 41 tests passed, covering DDL, final/empty results, execution modes, parameter binding, SQL quoting, failure atomicity, transaction rollback and result transformations.
• pnpm check, pnpm lint-fix and git diff --check passed.
• Includes a patch changeset for @effect/sql-pglite.
