fix(javascript): yield inside semantic analysis and large projection passes (#1542)

* fix(javascript): yield inside semantic analysis and large projection passes

After #1525 the longest event-loop blocks were single stages on very large
files: semantic analysis of Obsidian's 3.7 MB app.js ran 5.8 s in one piece,
and its object projection 1.8 s.

- analyzeParsedJavaScriptSemanticsSteps yields between the analysis phases
  and between the eight derived collectors; the synchronous function drains
  it, so results are unchanged.
- Per-file analysis yields between open-receiver classification and static
  analysis and drives the semantic steps.
- Semantic node creation, definitions and references, and the object and
  frontier passes yield every 64 items. Node creation keeps source order,
  which the per-file node budget depends on.

On obsidian.asar the longest block falls from 5,355 ms to 907 ms with the
same total time (40.6 s to 39.5 s). Graph IDs and complete result digests
match main on five inputs. Remaining blocks up to about 0.9 s are single
AST traversal passes inside the analyzers.
