Map NANOBOT_WEB_TOKEN to channels.websocket.tokenIssueSecret instead of
the static token, and remove the static token. The gateway now issues
short-lived WebSocket/API tokens rather than accepting a long-lived
credential directly at the handshake, matching the public-WebUI login
flow and documentation. Users still enter the same NANOBOT_WEB_TOKEN,
and websocketRequiresToken remains true.

The WebSocket channel also serves the WebUI over plain HTTP, so on a
public endpoint (e.g. a Render *.onrender.com service) the underlying
websockets library logs a full-traceback ERROR for every request that
isn't a valid GET handshake: HEAD probes ("unsupported HTTP method;
expected GET"), port scanners, uptime monitors, and TLS-to-plain-port
attempts. These are internet background noise, not server faults.
WebSocketHandshakeNoiseFilter already suppressed "opening handshake
failed" records caused by mid-handshake disconnects; widen it to also
suppress records whose exception chain contains websockets'
InvalidMessage, which covers both non-GET methods and malformed/empty
requests. Genuine server-side handshake errors still log.

- Updated entrypoint.sh to initialize the on-disk config only if it does not already exist, preserving user edits across restarts.
- Enhanced privilege dropping logic to ensure the container does not run as root if the privilege drop fails.
- Clarified comments in Dockerfile and entrypoint.sh for better understanding of the privilege management process.
- Updated README.md to include a note about persistent disks requiring a paid service on Render.
- Adjusted render.yaml to clarify the Docker command behavior and added a note regarding auto-deploy settings.
Adds a Render Blueprint (render.yaml) and supporting pieces so nanobot can
be deployed to Render in one click, with persistent memory across deploys.
- render.yaml: web service + 1GB persistent disk mounted at
/home/nanobot/.nanobot. Prompts for ANTHROPIC_API_KEY and
NANOBOT_WEB_TOKEN at deploy time (sync: false).
- render-config.json: committed gateway config that wires secrets via
${VAR} placeholders (resolved at runtime). Nothing secret is committed.
- entrypoint.sh: adds a branch gated on RENDER=true that copies the config
onto the mounted disk, chowns the root-owned mount, and drops to the
non-root nanobot user via setpriv. Local (non-Render) path is unchanged.
- Dockerfile: COPY render-config.json; USER nanobot -> USER root so the
entrypoint can chown the freshly-mounted disk before dropping privileges;
add PYTHONUNBUFFERED/PYTHONFAULTHANDLER for diagnosable crash output.
- README.md: Deploy to Render button + section.

jobs.json hand-edits and asdict-style snake_case for schedule intervals and
runHistory crashed or silently disabled cron. Deserialize via Cron* from_store_dict
and shared get_camel_snake (also used by local triggers).
Keep only 128 recently used sessions strongly cached while retaining weak references to evicted sessions still owned by active callers. This bounds idle memory growth without allowing duplicate live Session objects or skipping shutdown flushes.
Add LRU, lifecycle, SDK, and flush regression coverage.

When max_len is 0 or negative the cut pointer never advances, so the loop hangs. Return the content unsplit, matching truncate_text_to_tokens for non-positive budgets.
fe0717b3 ("feat(webui): add guided setup flows") added qrcode and
@types/qrcode to webui/package.json without regenerating the lockfile,
so `npm ci` fails in the Docker build with EUSAGE (Missing: qrcode,
@types/qrcode, dijkstrajs, pngjs, yargs, ...).
Regenerate the lockfile so it matches package.json again.

When an MCP server (e.g. stdio browser-agent subprocess) does not
terminate within the AsyncExitStack.aclose() timeout, asyncio raises
CancelledError. The existing exception handler only caught RuntimeError
and BaseExceptionGroup, so CancelledError escaped the except block and
crashed nanobot with exit code 1 on every shutdown.
Add asyncio.CancelledError to the caught exception tuple so the error
is logged at debug level and shutdown completes cleanly.
Stack trace from the crash:
Traceback (most recent call last):
File ".../nanobot/agent/loop.py", line 1194, in close_mcp
await stack.aclose()
asyncio.exceptions.CancelledError
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File ".../asyncio/__main__.py", line ?, in <module>
File ".../nanobot/agent/loop.py", line ?, in close_mcp
...
RuntimeError: ... (or BaseExceptionGroup) not caught
SystemExit: 1
