chore(cli): migrate index, scaffoldHandler, baremetalHandler, and deploy templates from JS to TS

[lisa-assistant]

Summary

Converts 10 JavaScript files in packages/cli/src to TypeScript:

• src/index.js → src/index.ts — typed getTomlDir param, error narrowing in catch
• commands/generate/scaffold/scaffoldHandler.js → .ts — ScaffoldField/ScaffoldModel interfaces, ListrTaskWrapper types, proper error narrowing
• commands/deploy/baremetal/baremetalHandler.js → .ts — ServerConfig, BaremetalYargs, LifecycleHooks interfaces, error narrowing in all catch blocks
• commands/setup/deploy/templates/baremetal.js → .ts
• commands/setup/deploy/templates/flightcontrol.js → .ts
• commands/setup/deploy/templates/netlify.js → .ts
• commands/setup/deploy/templates/netlifyUD.js → .ts
• commands/setup/deploy/templates/render.js → .ts — typed database: string param
• commands/setup/deploy/templates/serverless/api.js → .ts
• commands/setup/deploy/templates/serverless/web.js → .ts

Also removes @ts-expect-error suppression comments from 4 handler files that were silencing missing types from these now-converted template files.

Type safety

• No as any, no @ts-ignore
• Error narrowing follows e instanceof Error ? e.message : String(e) throughout
• as casts are limited to genuine typing boundaries (e.g. DMMF models from getSchema() return an opaque union type)
• Local interfaces (ScaffoldField, ScaffoldModel, ServerConfig, etc.) describe the actual shapes used

Test plan

• yarn workspace @cedarjs/cli tsc --noEmit passes (no new errors)
• Scaffold generator: yarn cedar generate scaffold Post
• Baremetal deploy handler unit tests: yarn workspace @cedarjs/cli test baremetal
• Deploy template imports verified in netlifyHandler, renderHandler, serverlessHandler, baremetalHandler setup

Greptile Summary

This PR converts several CLI files from JavaScript to TypeScript. The main changes are:

• TypeScript migrations for the CLI entrypoint and deploy handlers.
• TypeScript migrations for scaffold generation logic.
• TypeScript migrations for deploy setup templates.
• Removal of obsolete import suppression comments for converted template files.
• Narrower error handling in the changed CLI catch blocks.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.

Important Files Changed

Filename	Overview
packages/cli/src/commands/deploy/baremetal/baremetalHandler.ts	Migrates the baremetal deploy handler to TypeScript and preserves remote command exit codes in the deploy catch block.
packages/cli/src/commands/generate/scaffold/scaffoldHandler.ts	Migrates the scaffold handler to TypeScript and preserves generator exit codes in the scaffold catch block.
packages/cli/src/commands/deploy/baremetal.ts	Removes an obsolete suppression around the imported baremetal handler.
packages/cli/src/commands/setup/deploy/providers/baremetalHandler.ts	Removes an obsolete suppression for the converted baremetal deploy template import.
packages/cli/src/commands/setup/deploy/providers/netlifyHandler.ts	Removes obsolete suppressions for converted Netlify deploy template imports.
packages/cli/src/commands/setup/deploy/providers/renderHandler.ts	Removes an obsolete suppression for the converted Render deploy template import.
packages/cli/src/commands/setup/deploy/providers/serverlessHandler.ts	Removes obsolete suppressions for converted Serverless deploy template imports.
packages/cli/src/index.ts	Migrates the CLI entrypoint to TypeScript and narrows catch-block error output.
packages/cli/src/global.d.ts	Renames the global declaration file after the entrypoint migration.

Greptile P1/P2 on exit code handling are false positives — both baremetalHandler.ts and scaffoldHandler.ts already read exitCode, not errno:

const exitCode =
  e instanceof Error && 'exitCode' in e
    ? ((e as Error & { exitCode?: number | null }).exitCode ?? 1)
    : 1

This matches the original JS (e?.exitCode || 1). The NodeJS.ErrnoException in the error message block is just used as a type with a known stderr field — the errno property itself is never read.

Fixed CI failures in 1e94bb5:

Lint errors:

• baremetalHandler.ts: Added blank line between parent (../../../lib) and sibling (./SshExecutor) import groups (import-x/order)
• scaffoldHandler.ts: Array<{ name: string }> → { name: string }[] (@typescript-eslint/array-type); removed unnecessary as string assertion on validationDef (@typescript-eslint/no-unnecessary-type-assertion)
• index.ts: Split destructuring — cwd stays let (reassigned later), telemetry/help/version → const (prefer-const)
• Renamed index.d.ts → global.d.ts: TypeScript skips index.d.ts when index.ts exists in the same directory, which caused the parserOptions.project ESLint error

Prettier:

• Ran on baremetal.ts, baremetalHandler.ts, index.ts
