ref(database/sqlmigrate): extract migration library with shmigrate backend 
Factor the inline migration logic from cmd/sql-migrate into reusable
packages: database/sqlmigrate (core types, matching, file collection)
and database/sqlmigrate/shmigrate (shell script generation backend).

No behavior changes — the CLI produces identical output. The shmigrate
package implements the sqlmigrate.Migrator interface so other backends
(pgmigrate, mymigrate, etc.) can follow the same pattern.

sqlmigrate

Database-agnostic SQL migration library for Go.

Go Reference

Backend packages

Each backend is a separate Go module to avoid pulling unnecessary drivers:

Package Database Driver
pgmigrate PostgreSQL pgx/v5
mymigrate MySQL / MariaDB go-sql-driver/mysql
litemigrate SQLite database/sql (caller imports driver)
msmigrate SQL Server go-mssqldb
shmigrate Shell scripts (generates POSIX sh)

CLI

The sql-migrate CLI uses shmigrate to generate shell scripts for managing migrations without a Go dependency at runtime.
