Subject: [PATCH] ci: measure coverage of the installed package, so Codecov
 gets real data

The coverage job installs the package and runs the tests against the installed
copy, but told coverage to measure src/roboticstoolbox, which never runs:
"No data was collected", an empty report, and Codecov showing 0% on every commit
of main, with 16686 lines and no hits.

Coverage now measures the package by name, [tool.coverage.paths] maps the
installed files back to src/, and relative_files makes the report use the paths
of the repository, so that Codecov can match them.

Left out of the report: the Dynamixel and ROS sketches, the two DHFactor modules
that nothing imports, and bin/, which the tests run in a subprocess that coverage
does not trace.

.github/codecov.yml: no comment on each pull request, and the project and patch
statuses are informational.  Only "All tests passed" is a required check.
