## Summary
* **What is the goal of this PR?** (e.g., Fixes a bug in the user
authentication module, Implements the new feature for
file uploading.)
This PR refactors the semantic version comparison logic used during OTA
update checks.

Flash: [========= ] 85.7% (used **5616870** bytes from 6553600 bytes)
* **What changes are included?**
Replaced std::string::substr() and std::stoi() based parsing with a
lightweight, heap-free approach.
Version parsing is now done in a single pass without creating temporary
std::string objects.
Behavior remains identical: versions are still compared as
MAJOR.MINOR.PATCH.
## Additional Context
`std::string::substr() ` creates a new string and performs heap
allocation
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).
## Summary
* Adds support for OTA
* Gets latest firmware bin from latest GitHub release
* I have noticed it be a little flaky unpacking the JSON and
occasionally failing to start
