🔍 What was changed

• New «Migration Names» section: what NameBasedOnChangesGenerator (default) and ChangesCountNameGenerator produce, with real names from a run, how to switch to short names, and since which versions they exist.
• The custom name generator example now implements the real generate(Atomizer $atomizer) signature and builds the name from the atomizer's tables.
• The «Single File Strategy» example passes the required name generator to SingleFileStrategy.

Checklist

• Refs Shortening migration names for improved readability and understanding schema-migrations-generator#15
• How was this tested:
  • Every PHP block of the section was extracted from the Markdown and run on SQLite with schema-migrations-generator 2.3.0 / migrations 4.3.0; the names in the text are from that run
