fix: preserve completed chat responses after stream retry

[ironloopai]

Summary

• Treat a received final reply as successful completion for its run.
• Ignore a trailing retryable stream/replay error for that completed run.
• Add regression coverage for final_reply followed by replay_unavailable.

Validation

• corepack pnpm lint
• corepack pnpm test
• corepack pnpm build
• scripts/pre-commit-safety.sh

Rust crate tests were attempted but the environment has no cc linker. This is a frontend-only state-handling change; reverting the commit restores prior behavior.

---

Closes #6189.

Opened by IronLoop after verifying the local implementation branch.

This table itself is informational and never gates the PR on its own — not the percentage, not the per-crate holes, not the 0-coverage callout. A separate coverage ratchet (dry-run until enforce=true; see tests/integration/coverage-floor.toml) can fail the build on specific configured floors.

[serrrfirat]

Closing as superseded. #6337 changed retryable stream errors into transport interruptions that preserve the completed response/state, and #6876 further hardened reconnect behavior, so this PR no longer needs a separate final-reply tracker.
