Fix bin/migrate crash on the fs/promises import

[probablyian]

Summary

bin/migrate crashes before it connects to the database, so a fresh docker-compose setup never gets its tables. entrypoint.sh tries it 5 times, 10 seconds apart, then starts pulldasher against an empty database.

The ESM conversion in 48b6d14 imported readFileSync from fs/promises, which only has the promise versions, so Node refuses to load the script:

SyntaxError: The requested module 'fs/promises' does not provide an export named 'readFileSync'

This imports it from fs instead. Checked against MySQL 8.4.9 under Node 24: the script exits 0 and creates all 7 tables in migrations/schema.sql, and a second run also exits 0.

QA

• Point a config at an empty database and run node bin/migrate. Confirm it exits 0.
• Run SHOW TABLES on that database. Confirm it lists 7 tables.
• Run node bin/migrate again. Confirm it still exits 0.

QA 🟢

bin/migrate at 3681c77 builds the schema on an empty database and can run again without errors. Master's copy (2da5997) still fails with the error in the PR description. Ran under Node 24.21.0 against a throwaway MySQL 8.4.9.

Check	Result	Evidence
Master bin/migrate on an empty database	fails, exit 1	SyntaxError: The requested module 'fs/promises' does not provide an export named 'readFileSync'
First run on an empty database	pass, exit 0	output below
SHOW TABLES	pass, 7 tables	the same 7 that migrations/schema.sql creates
Second run on the same database	pass, exit 0	output below

Tested

• Point a config at an empty database and run node bin/migrate. Exits 0.
• Run SHOW TABLES on that database. Lists comments, commit_statuses, issues, pull_labels, pull_signatures, pulls, reviews.
• Run node bin/migrate again. Still exits 0.

Not tested

• docker-compose up, which runs the script through entrypoint.sh. The machine this ran on has no Docker.
