#2934 fix(cli): stop error-tracking noise from duplicate-version uploads

Summary

• Who it hurts: the team, not the user. A duplicate-version bundle upload — a normal outcome the user fixes by bumping the version — still minted an error-tracking $exception issue on every run, crowding out real CLI crashes.
• Last week's fix added CliUserError + a type filter in shouldCapturePosthogException, but Version X already exists was never wired into it: uploadFail threw a bare Error, which the message-substring filter never matched.
• The fingerprint made it worse — it hashed the minified top-frame symbol and the full install path, so the same abort split into a fresh issue per npx cache hash, bunx, pnpm store, and release.

Two small changes:

Area	Before	After
Upload aborts	uploadFail throws bare Error → captured	throws CliUserError → filtered by type
Plan-upgrade checks + app add	bare Error → captured	CliUserError → filtered
Fingerprint	fn:kind:name:symbol:filename:status	fn:kind:name:status
Graceful-exit warning	names --silent-fail (does not exist)	names --version-exists-ok

Behaviour kept intact: non-zero exit, the printed message, and the trackCommandFailed analytics events. Only the $exception capture goes away.

Why drop the frame instead of normalizing it: the CLI ships as one minified dist/index.js, so the top-frame symbol is renamed on every release and every frame's filename is the same install-path-prefixed index.js. Neither carries stable, discriminating signal — the command path, error kind, error name, and exit status do.

Test plan

• bun test/test-posthog-exception.mjs — added cases: CliUserError('Version X already exists') and Upload cancelled by user are not captured; fingerprint no longer contains the symbol or filename.
• bun test/test-init-app-conflict.mjs — isAppAlreadyExistsError still matches the reworded app add error (id moved to context, "already exists" kept in the message).
• bun test/test-plan-validation.mjs, bun test/test-trial-warning.mjs, bun test/test-analytics-error-category.mjs, bun test/test-app-created-source.mjs — all pass.
• tsgo --noEmit and oxlint clean.

Screenshots

Not applicable — no visible CLI output changes except the corrected --version-exists-ok flag name in one warning line.
