Add Pomodoro JS interpreter script

[lordbuffcloud]

Summary

• Follow reviewer guidance from Add Pomodoro JS interpreter script #2481 by shipping Pomodoro as a Bruce JS interpreter script instead of a built-in Clock module.
• Add sd_files/interpreter/pomodoro_t-embed.js so users can copy/run it from Bruce's Scripts menu without spending core flash space.
• Keep the standalone repo as the place for the native module variant and device-specific notes: https://github.com/lordbuffcloud/bruce-pomodoro

Test plan

• node --check sd_files/interpreter/pomodoro_t-embed.js
• git diff --check
• Verified the current Bruce interpreter tree exposes the required display, keyboard, audio, and led modules used by the script
• On-device smoke test in Bruce JS Interpreter on T-Embed / compatible board

User-facing change

\release-note
Scripts bundle now includes a Pomodoro timer script for Bruce JS Interpreter users.

Quick QA pass on this PR:

• Pulled sd_files/interpreter/pomodoro_t-embed.js from the fork branch.
• Ran node --check /tmp/pr-clean/pomodoro_t-embed.js successfully; syntax is OK.
• No status checks are currently reported on the PR.
• No open review comments are present yet.

Looks merge-ready from a code-sanity perspective; next blocker is maintainer review/merge access.
