fix: handle proper tokenization for --extra-params flag

[valeriobelli]

Summary

--extra-params was split naively on spaces (val.split(' ')), which broke any argument containing a legitimate space and leaked the quote characters through, e.g.:

  --extra-params='-destination "iOS Simulator" CODE_SIGNING_ALLOWED=NO'
  --extra-params='EXCLUDED_ARCHS="arm64 i386"'

Replace the split with a shared, quote-aware tokenizeCommand utility in cli-tools. It honors single/double quotes, joins adjacent quoted and unquoted segments into one token, and does no shell interpretation; values like OTHER_LDFLAGS=$(inherited) and Windows Gradle paths (C:\keys\app.jks) reach the tool verbatim. Empty/whitespace-only arguments yield no arguments, and an unterminated quote throws a clear error.

Wired into XcodeBuild (buildOptions) and Gradle (buildAndroid, which is also reused by run-android). The Xcode build log now quotes arguments containing whitespace so it stays copy-pasteable.

Additionally, the apple-related buildProject function accounts for this change when printing the generated xcodebuild command, enabling effective copy-and-paste.

Test Plan

Added tests in packages/cli-tools/src/__tests__/tokenizeCommand.test.ts asserting some use cases.

$ jest packages/cli-tools/src/__tests__/tokenize.test.ts
 PASS   unit  packages/cli-tools/src/__tests__/tokenize.test.ts
  tokenize
    ✓ splits space-separated xcodebuild arguments
    ✓ splits space-separated gradle properties
    ✓ keeps a double-quoted xcodebuild destination with spaces in one token
    ✓ keeps a single-quoted destination specifier with spaces in one token
    ✓ strips the surrounding quotes from a quoted path containing a space
    ✓ joins an unquoted build-setting name with its quoted, space-containingvalue
    ✓ collapses extra whitespace (spaces and tabs) between arguments
    ✓ passes xcodebuild build-setting syntax such as $(inherited) through verbatim
    ✓ keeps backslashes literal so Windows gradle paths survive
    ✓ returns an empty array for empty input
    ✓ returns an empty array for whitespace-only input
    ✓ drops a stray empty quoted argument
    ✓ throws on an unterminated double quote
    ✓ throws on an unterminated single quote
