v6.2.0

Bug Fixes

• Buffered startup logs now preserve original caller metadata. When an early log is held briefly for async package-name lookup, its @filename and @logCallStack are captured at the original call site instead of being recomputed later during flush.
• Node ESM caller detection now skips packaged library frames more reliably. @filename no longer falls back to node_modules/console-log-json/dist/esm/index.mjs in the reported startup case when the first real external caller is the consumer's app entry file.
• Bare Error stack headers are now stripped from non-error call stacks. @logCallStack no longer degrades to a useless literal "Error" when the runtime emits a header line without a trailing colon.
• Internal helper frames are omitted from @logCallStack. Non-error call stacks now start at the consumer-visible caller instead of internal helpers like captureFileInfo(...), emitConsoleJsonLog(...), or logUsingConsoleJson(...).

Tests

• Added end-to-end regression coverage for the reported Node ESM startup case. The test suite now verifies @packageName, @filename, and @logCallStack behavior with a temporary ESM consumer setup that mirrors the installed package layout under node_modules/console-log-json/dist/esm/index.mjs.
• Added stack-parser regressions for packaged ESM frames and internal helper trimming. Browser/stack compatibility tests now cover installed-package frame skipping, bare Error headers, and removal of leading internal logger helper frames from @logCallStack.
