Add prisma7 README and remove completed project artifacts

[StevenMcClankerton]

Adds the package-facing README for @prisma/prisma7 and removes the transient planning and review artifacts for the completed Prisma 7 compatibility CLI project.

Changes

• Document installation, the prisma7 executable, common commands, and the @prisma/prisma7/config import.
• Remove only projects/prisma7-compatibility-cli/; no long-lived project documentation needed migration.

All implementation slices have merged in #29949, #29969, #29994, #30000, and #30002.

Verification

• Rebased onto the current v7 branch after Rename prisma7 package to @prisma/prisma7 #30002 and the latest base update.
• Packed @prisma/prisma7 and verified the tarball contains package/README.md, package name @prisma/prisma7, and the unchanged prisma7 bin.
• Inspected the packed manifest: pnpm rewrites "prisma": "workspace:*" to the package's exact current version (0.0.0 locally). The publisher writes the common release version to each package before publishing, so release artifacts retain that exact lockstep dependency.
• Repository-wide scan found no references to projects/prisma7-compatibility-cli/ outside that directory.

📝 Walkthrough

Walkthrough

The README documents the @prisma/prisma7 compatibility package, including installation, prisma7 CLI commands, Prisma Config helpers, and lockstep versioning.

Changes

Prisma 7 compatibility package documentation

Layer / File(s)	Summary
Document package usage packages/prisma7/README.md	Documents package installation, CLI commands, Prisma Config usage, and exact-version dependency requirements.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Mergeability Score: 🔵 Low · up to 7d200

The README adds installation and dependency claims for @prisma/prisma7, but the supplied verification does not confirm that the published package manifest rewrites its placeholder version and workspace dependency to the intended Prisma 7 values. The PR is otherwise mergeable with explicit owner confirmation before publication.

[StevenMcClankerton]

Addressed the review risk around the README’s lockstep-version claim: the packed manifest rewrites prisma: workspace:* to the exact current package version (0.0.0 in the local pack), and scripts/ci/publish.ts writes the shared release version before each package is published. The PR description now records this evidence. There were no actionable inline review threads.
