docs: add release notes for audio stage name fix (PR #1470)

[lbliii]

Description

Adds a bug fix entry to the Fern 26.04 release notes for PR #1470, which fixed audio pipeline stage names not propagating in StagePerfStats. This made benchmark output unable to identify per-stage timing. The fix ensures all audio stages correctly report their names and preserve stage performance history.

Usage

N/A — documentation-only change.

Greptile Summary

This documentation-only PR adds a Bug Fixes section to the 26.04 Fern release notes, documenting the stage name propagation fix from PR #1470. The new entry is accurate — all four stage class names (GetAudioDurationStage, PreserveByValueStage, AudioToDocumentStage, GetPairwiseWerStage) are confirmed in the codebase, each with a correctly set name attribute. The placement between Dependency Updates and Breaking Changes is logical and follows the document's existing pattern.

Key changes:

• Added a ## Bug Fixes section heading
• Added a ### Audio Stage Name Propagation (PR #1470) subsection describing the fix accurately: stage names not propagating in StagePerfStats, and the _stage_perf history now being preserved when new task objects are created
• No code changes; no runtime risk

Confidence Score: 5/5

Safe to merge — documentation-only change with no code modifications and accurate technical content.

All stage names referenced in the release note entry are verified in the source code and have matching name attributes. The description accurately reflects the fix (stage names not propagating in StagePerfStats, and _stage_perf history being preserved). No P0 or P1 issues were found.

No files require special attention.
