test(export): rename the CLI source-surface test; list the six sources in the MCP tool text

test_export_cli_pi_omp.py was named for a harness pair that no longer exists
as such: omp is not a supported source, and the file's body never tested it --
it asserts the `--sources` / `--<source>-only` surface for the supported set
and that `--omp-only` / `--gemini-only` stay absent. The new name says what it
covers; all 20 assertions, including those three negative guards, are byte-
identical.

mcp_server.py's `session_search` docstring is the tool description an LLM
reads before choosing a filter; it still offered `gemini` and omitted grok and
pi. The module docstring listed five harnesses. Both now name exactly the six.
