v0.5.2

LaTeX rendering for Telegram: formulas now readable as Unicode text.

Added

• LaTeX to Unicode converter — LaTeX formulas like $500 \text{ г} \times 4 \text{ недели} = 2.0 \text{ кг}$ now render as readable text (500 г × 4 недели = 2.0 кг) instead of raw LaTeX code
• Math symbol support — Greek letters (α, β, π, Σ), operators (×, ÷, ±, ≤, ≥), arrows (→, ⟹), and trigonometric functions (sin, cos, tg)
• Typographic conversion — inch/foot marks like 1" and 6' automatically convert to 1″ and 6′ in formulas
• People v0.5.1 test coverage — 35 tests for People Graph functionality (extractForwardedPeople, performSearchPeople, performUpdatePerson, performMergePeople, performCreatePerson, performDeletePerson, applyPeopleUpdates)
• MockEmbeddingResponse helper — centralized mock for OpenRouter embedding responses

Fixed

• Data race between web server and webhook config — moved WebhookPath/WebhookSecret computation before web server creation to avoid concurrent read/write
