docs(cr-2026-04-22): add release-blocker issue tracker at docs/issues/

Captures the 12 items from docs/code-review-2026-04-22.md that
must land before v0.1 ships. One markdown file per issue with:
severity, path:line, problem description, acceptance criteria,
fix scope, and dependency graph.

Split by severity:
- 3 CRITICAL: live-session race, migration atomicity, transcript-
  profile FK
- 9 MAJOR: monolith refactor, channel-fatality, capture worker
  join, runtime capabilities, macOS App Nap, decoder error prop,
  LLM prompt preflight, keystore thread-safety, hotkey device
  filter

README.md indexes them with a fix-order dependency graph and a
fish-shell script for bulk-converting to GitHub issues once `gh`
CLI is installed and authed. Deferred step by user decision —
markdown tracker is authoritative until then.

+# RB-05 MAJOR: poll_inference treats IPC listener loss as session-fatal
+
+**Severity:** MAJOR
+**Path:** `src-tauri/src/commands/live.rs:721-813`
+**Source:** [2026-04-22 code review](../code-review-2026-04-22.md)
+**Labels:** release-blocker, major, ipc-lifecycle
+
+## Problem
+
+`result_channel.send(...)` propagates with `?`, so closing the listening frontend or reloading the webview terminates the whole live session — even when capture and inference are healthy. Tauri channel-lifecycle events are not transcription failures and should not kill the worker.
+
+## Acceptance
+
+- Channel-send errors log a warning and continue the session (if recoverable) or terminate gracefully (if the session was going to end anyway).
+- The distinction between "transcription failed" and "no listener to report to" is explicit in the error handling.
+- Regression test: simulate channel close mid-session, assert the worker keeps capturing and produces a valid WAV file.
+
+## Fix scope
+
+Medium. Isolated to `poll_inference` and its error handling; interacts with RB-04 (monolith refactor) since that restructures the same function family.
+
+## Dependencies
+
+- **Related:** RB-04.
