Add file watching feature for automatic retranslation

[maxprilutskiy]

WHAT

Implement a "watch" mode that automatically triggers retranslation when changes are detected in the source file.

WHY

• Saves time by eliminating manual retranslation after each edit
• Improves workflow for users working on iterative translations
• Keeps target language files in sync with source file changes

HOW

1. Monitor specified source file for changes via lingo.dev run --watch
2. When changes detected, trigger retranslation process
3. Implement debounce mechanism to avoid excessive retranslations on rapid changes

Hey Max, I was trying on adding a file in the @replexica/cli for the watch command , such that it changes the source file. However in the package json , there were these libraries from replexica which were causing me error while running npm i .

"@replexica/sdk": "workspace:", "@replexica/spec": "workspace:",

Any ideas what should i do to remove this error ?

[maxprilutskiy]

hey @bluzeey, we're using pnpm:

git clone https://github.com/lingodotdev/lingo.dev
cd lingo.dev
pnpm i
pnpm turbo build

# in terminal window 1
cd packages/cli
pnpm run dev # to start watching for changes in the cli code

# in terminal window 2
cd package
pnpm lingo.dev --help # this command will use the current cli code + demo config from ./package/i18n.json

feel free to ask questions on discord as well (lingo.dev/go/discord)

PR looks good. Let's go with 5s debounce, as you have in your PR. Testing it locally now.
