fix(hermes): add SQLite fallback for loadHermesSession (#535)

When sessions.write_json_snapshots is disabled, Hermes only writes to
state.db (SQLite). loadHermesSession now falls back to reading from
~/.hermes/state.db when the JSON file is missing.

- Add getHermesDbPath() and loadHermesSessionFromDb() functions
- Use bun:sqlite with readonly mode, try-catch for graceful errors
- JSON file still takes priority (fast path)
- Filter messages to user/assistant/tool roles
- Convert unix timestamps to ISO 8601 strings

+# E2E walkthrough for uncaged/workflow.
+# Runs inside Docker with isolated UNCAGED_WORKFLOW_STORAGE_ROOT.
+# Exercises: setup → workflow add → thread start/exec → cancel/fork → read/inspect.
+#
+# Usage:
+#   sudo -E scripts/e2e-walkthrough.sh [--agent <agent>] [--provider <provider>] [--model <model>] [--api-key <key>]
+#
+# Requires: Docker running, $HOME mount approach (see scripts/check-dev-env.sh).
+# Produces: JSON report on stdout, logs in $E2E_DIR.
+#
+# IMPORTANT: Must run with `sudo -E` to preserve $HOME (Docker needs root).
+#
+# Known Issues (WIP):
+#   1. `echo '$OUT' | jq` breaks when $OUT contains single quotes (e.g. workflow show
+#      output with YAML). Fix: use heredoc or pipe variable directly.
+#   2. Config may still have old `apiKeyEnv` field — thread exec will fail with
+#      "no API key". Fix: re-run `uwf setup` or manually set `apiKey` in config.
+#   3. Bootstrap installs jq via apt-get which adds ~30s startup time.
+#      Consider baking a custom image or using node's JSON.parse instead.
+#   4. `bun install` in container may modify host's lockfile/node_modules.
+#      Consider `--frozen-lockfile` or read-only mount for non-essential paths.
