/**
 * Anonymous, opt-out usage telemetry — VENDORED, kept byte-identical between
 * @extenshi/cli and @extenshi/mcp (same pattern as validate-artifact.ts). Edit
 * one, copy to the other.
 *
 * Why it exists: we want to know which commands/tools are used most, which fail,
 * and what errors recur — without shipping a heavyweight client or leaking PII.
 *
 * What it sends (and ONLY this):
 *   - command/tool name, surface ('cli' | 'mcp'), package + Node version,
 *     coarse os/arch, a CI bool
 *   - the NAMES of CLI flags used (never their values — see flagsFromArgv)
 *   - a coarse error_kind classification + durations
 *   - a path-redacted exception signature (message + stack, $HOME stripped)
 *
 * What it NEVER sends: file paths, artifact names/contents, API keys, manifest
 * data, or raw user input.
 *
 * Identity is an anonymous per-install UUID in ~/.extenshi/config.json
 * (`anonId`) — it identifies an install, not a person, and is never linked to
 * the API key client-side.
 *
 * On by default: the shared-project ingestion key is embedded (see
 * EMBEDDED_KEY), so telemetry is active unless the user opts out. Disabled
 * (no-op, never blocks the command) when ANY holds:
 *   - DO_NOT_TRACK is truthy (industry standard, https://consoledonottrack.com)
 *   - EXTENSHI_TELEMETRY in {0,false,off,no}
 *   - config file has "telemetry": false
 *   - the key is cleared (EMBEDDED_KEY emptied AND no EXTENSHI_POSTHOG_KEY)
 *
 * Everything here is fail-soft: any throw inside telemetry is swallowed so a
 * PostHog/network/disk problem can never break or slow the actual command.

 * surfaces also throw plain Errors). Order matters — status first, then
 * transport, then semantic buckets.
 *
 * Follows the `cause` chain, because both surfaces re-throw a failure wrapped in
 * an error of their own so it renders for the caller — the MCP tool layer wraps
 * in fastmcp's `UserError` (readError() in its tools.ts) — and the wrapper's own
 * message can carry no status. The origin hangs off `cause`, so an
 * unclassifiable wrapper defers to what it wraps; without this, a BFF 500 behind
 * a wrapper reads as `unexpected`.
