fix: add setMyCommands mock to telegram tests; fix husky hook to restage formatted files

- telegram.test.ts: add setMyCommands vi.fn() to the mock bot api so connect() doesn't throw
- .husky/pre-commit: add 'git add -u' after format:fix so prettier-reformatted files are
  included in the commit rather than left as unstaged changes (was causing CI format checks to fail)
