test(pipeline): the checks of the pure pipeline

Stream, Normalize, Merge, Dispositions, Config, CodeKeys and the pure half
of CommitsMode, each a test of its own (131 checks). The fixture rewrites
are checked in (code-keys/<name>/, commits3/), so the suite reads fixtures
and edits nothing. The allowlist, command-line and MCP checks of
CommitsMode come with the pool they test.

Among them: this binary's `<exe> sql` spelling counts as a SQL call, and a
result line with a raw U+2028 in a JSON string is still the result line.
