v2.0.0

Full port of every script and hook from bash + python3 to pure Node.js, so
the plugin runs identically on Linux, macOS, and Windows. No /bin/sh, no
bash, no python3, no GNU find — only node (already required by Claude
Code) plus bunx/npx for the one ccusage network call.

Changed (breaking — implementation only; commands & output are unchanged)

• All four scripts are now .mjs. scripts/probe.sh → probe.mjs,
  scripts/usage-snapshot.sh → usage-snapshot.mjs, scripts/setup.sh →
  setup.mjs, skills/usage/usage.sh → usage.mjs. The old .sh files are
  removed. Shared cross-platform helpers live in scripts/lib/mc.mjs (a
  PATHEXT-aware which, shell-free run, recursive newestFile, duration/bar
  formatting) and the wallet readers in scripts/lib/wallets.mjs (one source of
  truth for Codex / Claude / AGY data, used by both the full readout and the
  hook snapshot).
• Hooks switched to exec form. hooks/hooks.json now uses
  "command": "node" + "args": [...] (spawned directly, no shell) instead of
  "shell": "bash" with a $(find …) fallback — the documented cross-platform
  pattern. ${CLAUDE_PLUGIN_ROOT} is still substituted by Claude Code.
• /multiclaude:setup gained an idempotent apply mode. check (default)
  verifies and changes nothing; apply deep-merges the desired-state template
  into ~/.claude/settings.json (backing up to .bak, never clobbering keys it
  doesn't manage), with --full, --set dotted.key=value, --ttl, --model,
  and --dry-run. The JSON merge is native JS — the python3 heredoc is gone.

Removed

• python3, GNU find, and bash as dependencies. The usage readout's
  Codex and AGY sections read local files directly and now work fully offline;
  only the Claude block still needs the network (ccusage via bunx/npx).
