chore: release opencode-drive 1.4.0

[kitlangton]

What

Release opencode-drive@1.4.0 with provider-neutral runtime control for arbitrary native OpenCode tool lifecycles.

How

• Consumes .changeset/provider-tool-lifecycle.md.
• Bumps packages/drive/package.json from 1.3.0 to 1.4.0.
• Adds the generated 1.4.0 entry to packages/drive/CHANGELOG.md.

Scope

• Contains only generated Changesets release metadata for the already-merged PR feat(drive): control arbitrary tool lifecycles #42.
• Publishing remains tag-driven through .github/workflows/publish.yml; this PR does not publish directly.

Testing

• bun run release:validate: lint, typecheck, 30 Effect files / 202 tests, and package dry-run passed.
• bun run test:cli: 54 CLI integration tests passed.
• Packed opencode-drive-1.4.0.tgz: 95 files, 1.61 MB.
• Installed the tarball in a clean consumer and typechecked Tool.Controls.attach/take plus all seven public entry points.
• Imported every public entry point and ran opencode-drive --help from the clean consumer.
• Confirmed npm latest remains 1.3.0 before release.
