Fix TypeScript Type Truncation

Fixes TypeScript editors truncating types with "... N more" by increasing defaultMaximumTruncationLength from 160 to 16000 and defaultHoverMaximumTruncationLength from 500 to 50000.

macOS

Cursor:

sed -i '' -e 's/var defaultMaximumTruncationLength = 160;/var defaultMaximumTruncationLength = 16000;/' -e 's/var defaultHoverMaximumTruncationLength = 500;/var defaultHoverMaximumTruncationLength = 50000;/' '/Applications/Cursor.app/Contents/Resources/app/extensions/node_modules/typescript/lib/typescript.js'

VS Code:

sed -i '' -e 's/var defaultMaximumTruncationLength = 160;/var defaultMaximumTruncationLength = 16000;/' -e 's/var defaultHoverMaximumTruncationLength = 500;/var defaultHoverMaximumTruncationLength = 50000;/' '/Applications/Visual Studio Code.app/Contents/Resources/app/extensions/node_modules/typescript/lib/typescript.js'

Note: Restart editor after applying. Changes reset on app updates.
