- Add content/_schema/dialogue-line.schema.json — canonical standalone line schema
with all 6 structural + 3 selection + 2 authoring-only tags and $defs for
monologue extension (character, trigger, prerequisite)
- Update dialogue-pool.schema.json: add dual_lens and notes authoring-only tags,
add additionalProperties: false to knowledge_grant
- Update monologue-pool.schema.json: add all 6 structural tags as required fields
for schema compliance (role=player_character, access=[public], trust=surface are
constrained constants); add topic, mood, dual_lens, notes
- Enumerate all 14 v0.1 situations and 9 v0.1 topics as allowed enum values per D-035
- Fix Rust sync gap: add Situation::Greeting and Mood::Focused to line_pool.rs
(D-035 Sprint 8 amendments — were in schema but missing from Rust enums, causing
content with these values to be silently dropped at runtime)
- Update line_preview.rs situation_str, mood_str match arms and help text for
new variants; all 25 line_pool tests pass
