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-04 MAJOR: run_live_session is a 200+ line multi-responsibility monolith
+
+**Severity:** MAJOR
+**Path:** `src-tauri/src/commands/live.rs:349-579`
+**Source:** [2026-04-22 code review](../code-review-2026-04-22.md)
+**Labels:** release-blocker, major, refactor, concurrency
+
+## Problem
+
+`run_live_session` owns mic startup, runtime error draining, resampling, progressive WAV persistence, overload dropping, inference scheduling, and shutdown/finalisation in one 200-line function. The state machine is spread across mutable locals — hard to audit, hard to reason about under concurrency, and already contributing to lifecycle bugs nearby (RB-01, RB-05, RB-06).
+
+## Acceptance
+
+- Split into focused types / functions: capture setup, streaming state, inference scheduler, WAV writer lifecycle, shutdown handler.
+- Each function ≤ 30 lines, single responsibility.
+- State machine explicit — not implicit in the interleaved mutable locals.
+- Lock discipline documented: what must be held when, across what `await` boundaries.
+- Existing behaviour preserved — 193 workspace lib tests still green; manual dogfood smoke test of a 30-second live dictation.
+
+## Fix scope
+
+Large. Probably one dedicated session.
+
+## Dependencies
+
+- **Unblocks:** RB-01 (live session race fix becomes tractable once the state machine is small).
+- **Related:** RB-05, RB-06 (both lifecycle bugs in the same function).
