Add ErsatzTV.Core.Tests/Scheduling/Goldens/PlayoutBuildGoldenTests.cs — a
golden-file net that snapshots the PlayoutItems each builder produces over a
pinned build window; the scheduling counterpart to the M3U (#11) / XMLTV (#28)
goldens. This is the regression net that de-risks the scheduling-refactor
chain (#380 -> #70/#71/#176).
Coverage this slice:
- Classic (PlaybackOrder.Chronological)
- Block (TimeZoneInfo.Local-guarded to UTC via Assume: runs in CI, skips
gracefully under a non-UTC TZ; a real TZ seam is #380's scope)
Determinism: the builders read no wall clock (time enters only via the
caller-supplied start), so a pinned start is fully deterministic. Snapshots the
raw UTC Start/Finish, not the *Offset properties (which .ToLocalTime()). Regen
via ETV_UPDATE_PLAYOUT_GOLDENS (deliberately separate from ETV_UPDATE_GOLDENS).
Both goldens proven non-vacuous.
Sequential (YAML) + Scripted goldens tracked as a follow-up in #381.
Docs: docs/testing.md updated (third golden net + env var + Block TZ guard).

Adds docs/testing.md as the authoritative testing map (consolidated
from docs/contributing.md §8, now shrunk to a pointer), and a
generated docs/endpoint-index.md via scripts/generate-endpoint-index.py
(hooked into scripts/update-openapi.sh). Updates docs/README.md's
reading order and removes the "still to come" placeholder.
