chore: release v0.13.3

[nordicnode]

🤖 New release

• skillpack: 0.13.2 -> 0.13.3

Changelog

0.13.3 - 2026-08-15

Added

• add 8 languages, remove command, and 4 rules-directory targets

Fixed

• (ci) make multi-skill test git-identity-independent and unblock release PR
• honor intent-driven CLI rendering, multi-skill/update artifacts, distribution hardening

Other

• list Qoder, Continue, Augment, and Amazon Q as supported agents

Added

• Eight new language ecosystems: Lua (*.rockspec), Julia
  (Project.toml), Crystal (shard.yml), Clojure (deps.edn /
  project.clj), OCaml (dune-project / *.opam), Erlang
  (rebar.config / *.app.src), R (DESCRIPTION), and Perl
  (cpanfile / Makefile.PL / META.json) — with manifest name/version/
  author/license parsing, category/globs hints, and CLI candidates.
• Expanded Dart (CLI detection + pubspec.yaml name/version/authors) and
  Haskell (CLI detection + .cabal name/version), and Nix flake.nix
description capture as a description-hint fallback.
• skillpack remove <name> — the symmetric counterpart to add: drops a
  skill from skillpack.toml, deletes its orphaned per-skill files, and
  regenerates the remaining targets.
• Four new agent ecosystems: Qoder (.qoder/rules/), Continue
  (.continue/rules/), Augment Code (.augment/rules/), and Amazon Q
  Developer (.amazonq/rules/) — plain-markdown workspace-rule targets,
  taking the supported agent count from 14 to 18.
• verify --format json now self-identifies with $schema and
  schemaVersion fields (matched by verify-report.schema.json), and
  doctor --format json gained a verify_category_preview field.
• A schemas CI job meta-validates both committed JSON Schemas and checks a
  representative report instance (via scripts/validate_schemas.py).

Fixed

• owner_type is now validated at config-load time (only individual or
  organization) instead of letting the renderer emit any string.
• allowed_tools hint is now keyed off has_cli (pure-library skills no
  longer get a Bash hint), and derived marketplace keywords are capped at
  16 so a deep CLI subcommand tree can't bloat the marketplace entry.
