BUG: Fleet-synced session renders inline file links to remote-machine files as clickable, but nothing opens

[aarontrowbridge]

Summary

In a fleet-synced chat session, inline links to files (specs, design notes,
etc.) that live on another machine in the fleet render as clickable links —
but clicking them shows nothing, because the file paths don't exist on the
local machine. The affordance is silently dead.

Context

• Extension: harmoniqs.amicode 0.3.7 (linux-x64)
• Engine pin: v1.17.3-amicode.4 (harmoniqs/opencode)
• OS: Linux 7.1.1 x86_64
• Chat transcripts produced on the fleet's central server reference file
  paths under that machine's filesystem; when the session is viewed from a
  different fleet machine, those files are absent locally.

Expected vs actual

• Expected: the link either resolves the file through the shared
  fleet/vault storage (or a remote fetch/preview), or the UI indicates the
  file isn't available locally — not a clickable affordance that silently
  does nothing.
• Actual: the link renders clickable; clicking shows no file and no
  explanation.

Diagnostics

• No active run — no run-id pointer applicable.
• Extension 0.3.7, engine v1.17.3-amicode.4, Linux 7.1.1 x86_64.
• Symptom observed in fleet-synced session chat (links authored on the
  remote machine).
• No absolute paths, binaries, or vault contents attached.
