v0.13.1

Added

• expand agent ecosystem coverage and power-user tooling

Fixed

• harden distribution assets and default refresh to present targets
• harden verify, config, and add against silent corruption

Added

• Native Claude Code skills directory: the Claude target now also emits
  .claude/skills/<name>/SKILL.md (auto-loaded with no plugin install step).
• Four new ecosystem targets: Cline (.clinerules/<name>.md), Roo Code
  (.roo/rules/<name>.md), Kilo Code (.kilocode/rules/<name>.md), and
  Goose (.goose/instructions.md) — --target all now covers 14 formats.
• skillpack add <name>: append a skill to an existing pack (interview or
  --non-interactive bootstrap) and regenerate.
• --target list: print the canonical --target values.
• --format json for init/update/diff: machine-readable summaries for CI.
• verify --format github: GitHub Actions ::error/::warning annotations
  for inline PR-diff comments.
• skillpack config + config --validate: summarize/validate the committed
  skillpack.toml; a JSON Schema ships at skillpack.schema.json.
• Derived-field overrides in skillpack.toml: allowed_tools, category,
  globs, opencode_mode, and keywords can pin the language-derived values.
• Polyglot monorepo detection: introspect records secondary_languages and
  init --auto emits one skill per detected language.
• One-command install.sh + a Homebrew formula (homebrew/skillpack.rb) and a
  static x86_64-unknown-linux-musl release binary.

Fixed

• init re-running on a hand-authored [[skills]] pack no longer collapses it
  to the primary skill (it now renders every skill).
• Subcommand capture now honors a total --help spawn budget (breadth cap),
  truncating wide CLIs instead of forking thousands of probes.
• Subcommand parsing now recognizes cobra (Available Commands:) and argparse
  ({cmd1,cmd2} usage) help shapes, not just clap.
• command_from_documented no longer reads surrounding prose as the program
  name (a secondary skill used to resolve to CLI `The`).
• Version drift now genuinely tolerates a CLI that prints --version and
  exits non-zero (captured output is carried through RanNonZero).
