chore: enforce pnpm 11

[Sheraff]

Summary

Adds a root engines.pnpm requirement of >=11.0.0 alongside the existing exact packageManager declaration.

What This Blocks

• Blocks pnpm versions below 11 from running the repo's install workflow when that older pnpm binary is the one actually executing the command.
• Blocks pnpm versions below 11 from running pnpm run project-script workflows when that older pnpm binary is the one actually executing the command.
• Produces pnpm's ERR_PNPM_UNSUPPORTED_ENGINE error with the expected range and actual pnpm version for those guarded paths.
• Covers cases where packageManager is not honored as an automatic handoff to pnpm 11+, or that handoff is explicitly disabled.

What This Does Not Block

• Does not force the exact pnpm@11.1.0 version. The engine range allows any pnpm >=11.0.0; the existing packageManager field remains the exact version hint for tools and pnpm versions that honor it.
• Does not necessarily error for every pnpm 10 invocation. A direct pnpm 10 binary can honor packageManager and hand off to pnpm 11.1.0 before running the command; in that case the command succeeds under pnpm 11 rather than failing under pnpm 10.
• Does not fully intercept every possible pnpm subcommand once an older pnpm binary is already executing. In local checks, pnpm list and pnpm exec still ran under pnpm 9/10.
• Does not auto-upgrade a globally installed pnpm. Users with pnpm 9/10 installed directly still need their tooling to honor packageManager, or they need to install/invoke pnpm 11+.
• Does not add engineStrict; the blocking behavior here comes from pnpm honoring the project engines.pnpm field for install and run workflows.

Verification

• pnpm install --lockfile-only --frozen-lockfile --ignore-scripts succeeds with pnpm 11.1.0.
• A direct pnpm 9.15.9 binary fails pnpm install --lockfile-only --frozen-lockfile --ignore-scripts with ERR_PNPM_UNSUPPORTED_ENGINE.
• A direct pnpm 9.15.9 binary fails pnpm run with ERR_PNPM_UNSUPPORTED_ENGINE.
• A direct pnpm 10.0.0 binary reports pnpm 11.1.0 inside this repo by default because it honors packageManager and hands off to the declared package-manager version.
• With that pnpm 10 handoff disabled via npm_config_manage_package_manager_versions=false, pnpm 10.0.0 fails pnpm install --lockfile-only --frozen-lockfile --ignore-scripts with ERR_PNPM_UNSUPPORTED_ENGINE.
• With that pnpm 10 handoff disabled via npm_config_manage_package_manager_versions=false, pnpm 10.0.0 fails pnpm run with ERR_PNPM_UNSUPPORTED_ENGINE.
• Direct pnpm 9/10 checks also confirmed pnpm list --depth 0 and pnpm exec node -e "console.log('ok')" are not blocked by this field.
