Commit: yaml: documents with their markers, and a flow flag on each node (#928 step 4, ADR-yaml-1 D7)
Body: Node gets pub flow: bool: true for a flow sequence or mapping, including the single pair [a: b]. A node that takes its properties copies flow from its content. documents(input; limits) gives Vec[Document] (root, start for ---, end for ...) and throws the same size and depth errors. The grammar’s Docs rule moves each document into the list with drain(), so no node is copied: each further document records whether a ... came before it, and the stream’s last ... ends the last document. parse is now documents with each root taken out by drain(), with no second parse. Test document_markers covers markers, spans and flow; its expected output was checked by hand.
Part: #928
Tests: packages/yaml 15 passed (all 14 existing tests have the same output byte for byte, plus the new document_markers); fmt::every_nika_file ok; pre-push-check ok; Probe A of y22 prints 1 hello

Deviation: steps 2 and 3 (events, event_line, tests/events.nika) not built; blocked on the gap under Found
Found: for a scalar that resolves to Null, Bool, Int or Float, the tree drops what the suite’s =VAL line needs. Null and Bool drop their raw text (~, NULL and True give the same nodes as null and true). A tagged quoted scalar drops its quote style (!!int "1" becomes Int(1), and its span starts at the tag). Probe: parse [~, null, NULL, true, True, !!int "1"] and print each item’s value: Null Null Null Bool(true) Bool(true) Int(1). The suite wants =VAL :~, =VAL :NULL, =VAL :True, =VAL <tag:yaml.org,2002:int> "1. Following D7 the fix is to keep this in the tree as written, but where (a raw and style on Node, or payloads on Value::Null and Value::Bool, which changes every match) is a public API choice the brief does not make
