feat(pipeline): the pure pipeline, checked against its goldens

The modules that turn a frozen range into passes and passes into a
verdict: :Schema, :Tools (the DENY, git and base lists, a leaf, so the
config and the pool both read them), :Plan, :Artifact, :Inventory,
:Dispositions, :State, :Normalize, :Stream, :Prompt, :Config, and the URL
half of :PgWire. Units, jobs, results, the config and the claude stream
stay JSON from end to end, so every key keeps its place; :Text gives JSON
values truthiness, get, ==, membership and Str(), and throws Dyn::Error
under a name for each kind of unexpected data.

Exactness where the bytes are seen:
- the stream classifiers are hand-written scanners with case-insensitive
  folds (the Kelvin sign is a k), Unicode \b and \s, and `.` stopping at
  \n; the SQL call detection takes `<exe> sql` with any path before it;
- config problems carry the JSON scanner's and the UTF-8 decoder's own
  texts, positions included;
- a float total is Neumaier's compensated sum, and the build passes
  -ffp-contract=off: -march=native would fuse a*b+c;
- `crafter-review inventory` and `config` print what the goldens record,
  byte for byte (the fixture and 14 configs, broken ones included); a
  message names this binary as the command to run.

tests/Goldens: the recorded answers over the fixtures next to them (the
commits fixture, a rich versioned series with CRLF, a folded subject,
Markdown headings in and out of fences, the code-key rewrites); the suite
compares 2304 results as DumpFile writes them, so a key out of order fails
too. All agree.
