v1.13.1: chore: release 1.13.1

[1.13.1] - 2026-07-02

Logseq Matryca Parser 1.6.0 alignment

Changed

• logseq-matryca-parser — minimum dependency raised to 1.6.0 (from >=1.4.0); inherits 1.4.2 agent-write newline splice safety, resilient X-Ray state reload, SYNAPSE cyclic-embed truncation, plus 1.6.0 Clean Architecture graph APIs (iter_attached_nodes, is_tracked_markdown_path).
• _headless_append_child — normalizes source files missing a trailing newline before line splice (parity with parser 1.4.2); uses per-node tab_size_for_node for indentation.
• load_alias_registry — maps parser SessionAliasRegistryError (1.4.2+) to the existing corrupt-state ValueError contract.
