v0.15.2: GCF primer accuracy (spec v3.2) Patch release. Corrects the GCF format primer embedded in agent-lsp's MCP server instructions so LLMs parse tool responses accurately from the first call.

Fixed

• Nested-object flattening path syntax — the primer now explains that a quoted header column like "caller>name" is a flattened nested path that decodes to {caller: {name: ...}}. This is the common shape for blast_radius callers, diagnostics, and explore_symbol output under gcf-go v1.3.1 (spec §7.4.6).
• Null vs. missing tokens — corrected to match spec §7.4.2: - is explicit null, ~ is an absent key. (Previously conflated as one.)
• ^ attachment marker — documented that ^ in a row cell marks a variable-shape or array value attached as an indented .fieldname block, with schema reuse across rows. No code behavior changes — output encoding is unchanged. This only sharpens the instructions the model reads at session start. GCF: gcformat.com · Spec v3.2 · gcf-go
