feat(functions): rewrite deploy to per-function API with zero-config

[yardend-wix]

Note

Description

This PR refactors the functions deploy command to deploy each function individually (per-function API endpoint) instead of in a single batch request. It adds support for deploying specific functions by name, a --force flag that prunes remote functions not found locally, and per-function progress output with timing and status (deployed/unchanged/error).

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Refactoring (no functional changes)
• Other (please describe):

Changes Made

• API layer: Replaced batch deployFunctions (PUT /backend-functions) with deploySingleFunction (PUT /backend-functions/:name); added listDeployedFunctions reordering
• Schema: Renamed DeployFunctionsResponseSchema → DeploySingleFunctionResponseSchema with simplified { status: "deployed" | "unchanged" } response shape
• Core deploy logic: Replaced pushFunctions with deployFunctionsSequentially that deploys one-by-one with onStart/onResult callbacks; added pruneRemovedFunctions to delete stale remote functions
• CLI command: Added [names...] positional argument for targeted deploys; added --force flag to delete remote functions absent locally; replaced spinner with per-function progress logs showing name, status, and timing
• New helpers: formatDeployResult.ts for per-function output formatting; parseNames.ts for comma-separated name parsing
• Tests: Updated all mocks to per-function endpoints; added tests for unchanged status, deploy by name, name-not-found error, and --force + names conflict validation

Testing

• I have tested these changes locally
• I have added/updated tests as needed
• All tests pass (npm test)

Checklist

• My code follows the project's style guidelines
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation (if applicable)
• My changes generate no new warnings
• I have updated docs/ (AGENTS.md) if I made architectural changes

Additional Notes

Per-function errors are now soft failures — a single function's deploy error is captured and reported in the summary without aborting the rest of the deploy. The --force flag is intentionally incompatible with named deploys to prevent accidental deletions.
