What does this PR do?

• Problem: three small faults remain before the 3.0.0 tag. The README usage line for withTextFilepath has a ) in the wrong place, so it does not show valid Swift. The README does not show that strings() with no prefix returns every string. The podspec starts with a blank line. Also, the default branch is now main, but CI still runs on pushes to master only, so merges get no CI run.
• This PR:
  • moves the ) to the end of the withTextFilepath usage line and adds a strings() example (525ce1d).
  • removes the blank first line from the podspec (c4b869d).
  • runs CI on pushes to main (62f6da4). CI on pull requests does not change.
• Risk: none for library users. No Swift source changes.

Test Evidence

Run locally on 62f6da4 with Xcode 27.1:

Check	Command	Result
Unit tests	swift test	108 passed, 0 failed
Podspec lint	pod lib lint --platforms=macos,ios	passed
Workflow lint	actionlint .github/workflows/ci.yml	no issues
README example	a temporary test of the new strings() example	returned ["act", "apologise", "apology", "app", "apple"], as the README says

The CI run adds the full pod lib lint with tvOS.
