* feat(harness-plugin-core): simplify telemetry headers and HOME-first config path
- Identity is three headers: X-Honcho-Host `name/version (platform)`,
X-Honcho-Plugin `name/version`, X-Honcho-Agent-Model. X-Honcho-Runtime is
dropped. TelemetryIdentity gains `plugin` and `platform`.
- configPath() resolves env.HOME (then USERPROFILE) before os.homedir(), since
Bun's homedir() ignores in-process HOME changes and plugin tests were hitting
the real ~/.honcho/config.json.
- Extensionless internal imports so consumers no longer need
allowImportingTsExtensions to type-check against the source exports.
