Add uv.lock as a TOML file

[edgarrmondragon]

Description

uv.lock is a human-readable TOML file but is managed by uv and should not be edited manually.

Checklist:

• I am adding a new extension to a language.
  • The new extension is used in hundreds of repositories on github.com
    • Search results for each extension:
      • https://github.com/search?type=code&q=NOT+is%3Afork+path%3Auv.lock
  • I have included a real-world usage sample for all extensions added in this PR:
    • Sample source(s):
      • https://github.com/edgarrmondragon/uv-click-example/blob/ce8dbff4f7b16e50b159b0cb46b00bd2ee8357b3/uv.lock
    • Sample license(s): MIT
  • I have included a change to the heuristics to distinguish my language from others using the same extension.

Your sample is being surpressed by the diff because of its size which means it's too big for us. Please replace it with a smaller real-world sample.

FWIW regarding Pending Popularity , there were ~150 repos with a uv.lock file in search results this morning and we're at 183 now, so it's safe to assume the ecosystem will quickly reach the "hundreds of repositories" threshold.

Wow! A jump of several hundred in a week. Nice.
