humanize v0.3.0

Added

• Agent Plugins 1.0 manifest (plugin.json) and Codex manifest (.codex-plugin/plugin.json),
  so the plugin installs into Codex, Cursor, and Hermes with their own tooling.
• tests/test_portability.py: spec-only frontmatter, no harness-specific content under
  skills/, runtime references named, guard-clean scripts, manifests and CHANGELOG in
  version lockstep, zip packager contract, study count matches SOURCES.md.
• tools/package_skill_zip.py: builds the claude.ai skill upload from the plugin.
• tools/smoke_harnesses.sh: local acceptance matrix with scanner-evidence PASS rule;
  transcripts under docs/acceptance/v0.3/.
• README install table for Claude Code, Codex CLI, Cursor, Hermes Agent, Claude Desktop.

Changed

• Repository layout: the plugin now lives at the root (skills/humanize/); the marketplace
  source is ./.
• SKILL.md is harness-agnostic: relative scripts/surface_scan.py path, plain-words options,
  document extraction described generically; argument-hint removed (a hard error outside
  Claude Code). The /plugin install lines moved to the README.
• Public copy describes humanize as grounded in the thirteen studies in
  references/SOURCES.md and covering every layer of a text; StoryScope is named where it is
  the source of a number.
• pyproject.toml version now tracks the plugin version.

Migration

• Existing Claude Code installs: claude plugin marketplace update humanize && claude plugin update humanize@humanize.
