Weekend dependency sweep + CI fixes

Maintenance and security

• Ruby sweep: bumped parallel to 2.1.0 and rubocop to 1.86.1 across:
  • irasutoya-tools/irasutoya, irasutoya-tools/irasutoya-cli, circleci-tools/circleci-cli, bitflyer-tools/bitflyer, bitflyer-tools/bitflyer-cli.
  • This unblocked failing Dependabot runs that were erroring with “Error processing parallel (RuntimeError)”.
• Electron app security: forced tar@^7.x via overrides to clear a CVE that electron-forge was pinning us behind. Merged cycle-flyer #872.

CI and build

• Android deploy OOM: bumped CircleCI resource_class to large and tuned JVM/Gradle settings just for deploy. Merged DroidFlyer #510.
• Kicked the tires on migrating CI from CircleCI to GitHub Actions for Norimaki and DroidFlyer, opened PRs, then closed them without merging. Keeping it on hold for now.
• CircleCI library tests: updated the v2 Job mock to pass jobNumber and projectSlug so tests compile again (merged internally).

Testing and tooling

• Swapped out kspec/expekt for Kotest 6.1.11 in Norimaki. Cleaner assertions and JUnit 5 runner. Merged Norimaki #428.

Reviews and cleanup

• Reviewed/approved a handful of PRs across repos (cycle-flyer, Norimaki, DroidFlyer, CircleCI).
• Pruned a pile of stale branches (mostly old Dependabot branches) after merges.

Misc

• Starred orhun/ratatui-splash-screen — neat little TUI splash idea.
• GitHub stats ticked up: +2 followers, +1 following.
• Quiet elsewhere today: nothing on Linear or Bluesky.
