feat(many): migrate from npm to pnpm Phase 1

Implement Phase 1 of pnpm migration with workspace protocol and core tooling updates:

Configuration:
- Add pnpm-workspace.yaml defining workspace packages
- Add .npmrc with pnpm configuration (hoisted node linker, strict peer deps)
- Update lerna.json to use pnpm as npm client
- Update root package.json with pnpm engines, overrides, and devDependencies
- Update .gitignore for pnpm artifacts
- Delete package-lock.json (replaced by pnpm-lock.yaml)

Workspace Dependencies:
- Convert all internal @instructure/* dependencies from exact versions to workspace:*
- Update 94 package.json files across all packages
- Create scripts/convert-to-workspace-protocol.js for automated conversion

Build Tooling:
- Update scripts/bootstrap.js to use pnpm and run builds sequentially
- Update packages/ui-scripts/lib/commands/bump.js to use pnpm install
- Update packages/ui-scripts/lib/utils/npm.js to use pnpm whoami
- Fix babel-plugin-transform-imports for pnpm workspace module resolution
- Fix generate-all-tokens for pnpm workspace package resolution
- Add --skipOptimization flag to build-icons to prevent SVGO from modifying source files

CI/CD:
- Update all GitHub Actions workflows to use pnpm
- Add pnpm/action-setup@v4 with version 10.0.0
- Update caching to use pnpm lock files
- Configure registry-url for npm publishing

TypeScript References:
- Fix TypeScript project references in 10 packages (ui-drawer-layout, ui-expandable,
  ui-file-drop, ui-instructure, ui-link, ui-number-input, ui-popover, ui-radio-input,
  ui-text-area, ui-text-input)
- Add missing tsconfig.build.json references to match package.json dependencies

Temporary Workarounds (documented with TODOs):
- Add babel.config.js to use relative path for preset (pnpm resolution issue)
- Add webpack aliases in Cypress and Next.js configs for workspace packages
- Disable SVGO optimization in build-icons with --skipOptimization flag
- Skip TypeScript type builds in bootstrap due to missing dependency declarations

Regression Test Updates:
- Update regression-test app to use @instructure/ui meta package
- Convert all component imports to use single import from @instructure/ui
- Add scripts/update-regression-test-imports.js for automated import conversion
- Update InstUISettingsProvider import path

Documentation:
- Add pnpm-migration-plan.md with complete migration strategy
- Add pnpm-phase1-test-plan.md with testing procedures
- Add pnpm-phase1-investigation.md analyzing implementation
- Update building-instui.md and contributing.md with pnpm instructions

Notes:
- All Babel builds and token generation working successfully with pnpm
- Phase 2 will focus on fixing phantom dependencies and removing workarounds
- Some packages import types without declaring dependencies (Phase 2 cleanup needed)
