Rename the project to claude-code-account-rotation everywhere (repo, executable, app data directory, docs) #5

Summary

Rename the project from account-rotation to claude-code-account-rotation everywhere: the GitHub repository, the executable and product token, the per-user app data directory, the documentation, and the local checkout paths. The tool moves Claude Code's own ~/.claude/.credentials.json and patches ~/.claude.json; it does not touch Claude Desktop, so the name should say which product it rotates.

Why

account-rotation on its own does not say what is being rotated. The app data directory (%LOCALAPPDATA%\account-rotation, XDG account-rotation), the User-Agent product token, and the repository name all surface the bare name to the user and to Anthropic's servers.

Scope (everything that carries the name)

• GitHub repository melodic-software/account-rotation → melodic-software/claude-code-account-rotation, through github-iac (GovernedRepositories.cs); confirm the Pulumi GitHub provider renames in place rather than replacing the resource, and re-check the melodic-standards-sync App installation grant and the standards sync-manifest.yml entry after the rename.
• ConfigurationDefaults.ProductToken (account-rotation): the app data directory name and the honest User-Agent product token.
• AssemblyName account-rotation (the executable name) in src/AccountRotation.App/AccountRotation.App.csproj.
• Solution, project, and namespace names (AccountRotation.slnx, AccountRotation.Core, AccountRotation.App, AccountRotation.*.Tests): decide whether they follow the product name (ClaudeCodeAccountRotation.*) or stay as the short internal name; record the decision here.
• README.md title and posture section, docs/topics/claude-subscription-rotation/PLAN.md, tests/acceptance/README.md, REVIEW.md, CHANGELOG if present, and the CI workflow display names.
• eng/check-no-machine-paths.sh and any fixture or test that names the app data directory or product token.
• Existing per-user state: config.json, state/live-owner.json, state/switch-journal.json, instance.lock, and quarantine/ under the old app data directory. Either migrate the old directory on first start or document the one-time move in the README.
• Local checkouts and worktrees (D:\repos\github.com\melodic-software\account-rotation, .work/handoffs/*-account-rotation.md topic names) and the Claude-Session handoff resume prompts that cite the old path.
• Sweep with /docs-hygiene:rename-references audit after the rename for stale slash-tokens, paths, and table rows.

Not renamed

• ~/.claude-profiles (the parked-profile root) and ~/.claude are Claude Code's own naming and stay as they are.
• The Anthropic-side User-Agent contract does not change; only the product token value does.

Timing

Do this after #3 (Phase 1) merges and before Phase 2 starts, so the rename is one squash commit that does not conflict with an open feature branch. Phase 5's publish and release workflow then ship under the final name.
