hermes - 💡(How to fix) Fix Telegram MEDIA audio attachment can report success while delivering no attachment [1 pull requests]

Bug Description

Telegram MEDIA:<path> delivery can report success while the user receives only text and no playable audio attachment. This is a regression in a high-value gateway capability: archived Chronicle/voice-episode audio must be attachable from the canonical archive path, not silently dropped.

Observed Evidence

• User-visible failure: message said the official teaser was published, but no attachment appeared in Telegram.
• Gateway log showed the real failure earlier in the path:
  • Skipping unsafe MEDIA directive path outside allowed roots
• The tool response still surfaced success because the text portion was sent after media filtering removed the attachment.
• Direct Telegram Bot API retry worked from the same file:
  • endpoint: sendVoice
  • result: ok: true
  • message_id: 1219
  • returned voice.duration: 152, mime_type: audio/ogg, file_size: 827183

Reproduction Shape

1. Have a valid Ogg/Opus file under a durable archive path such as ~/.hermes/voice-episodes/.../teaser.ogg.
2. Send a Telegram message through Hermes containing:
   • [[audio_as_voice]]
   • MEDIA:/home/<user>/.hermes/voice-episodes/.../teaser.ogg
3. Observe whether Telegram receives a native voice/audio attachment.
4. Compare the result to a direct sendVoice call with the same file.

Expected Behavior

• If a MEDIA directive is accepted, Telegram receives a playable attachment.
• If a MEDIA directive is rejected, the user/tool result must clearly report attachment failure, not plain-message success.
• storage.safepath / operator-approved archival roots should be honored for media delivery after gateway/service restart.

Actual Behavior

• The user got no attachment.
• The assistant/tool reported success based on the text send.
• The failure became visible only through gateway logs or direct user complaint.

Acceptance Criteria

• Add a regression test for Telegram [[audio_as_voice]] + MEDIA:<canonical archive path> delivery or at least media extraction/filtering result propagation.
• Ensure dropped media produces a warning/error in the returned result, not a false successful attachment claim.
• Add an operator-facing self-test command/script or documented probe that performs a real Telegram sendVoice/sendAudio smoke test after updates.
• Verify storage.safepath and HERMES_MEDIA_ALLOW_DIRS behavior in both gateway auto-delivery and send_message tool paths.

Timeline / Chronicle Note

This was encountered during Miadi Chronicle teaser publication and should remain part of the Iris/Hermes co-agency update timeline: an update/security tightening broke or obscured a core creative workflow until the user caught it in the field.
