docs: add paste service to Workflow; clarify app-log vs stdout in Deploy

- Workflow: paste.rethinkstudios.io pastebin section — pb() function
  (recommended) + alias alternative in content tabs, usage, expires note,
  creation rate-limit warning.
- Deploy: warning admonition distinguishing ${LOGS_DIR} (app logger, to
  disk) from container stdout/stderr where startup crashes and uncaught
  exceptions land; sys.excepthook snippet to route them into the log file.

+## Paste service
+
+A shared, self-hosted pastebin at
+[paste.rethinkstudios.io](https://paste.rethinkstudios.io) — for quickly sharing
+logs, snippets, or command output when you're pairing, filing an issue, or handing
+output to a coding agent. Pastes are **unlisted** (random URL), **expire** by
+default, and support **burn-after-read**. Anonymous — no login.
+
+The easy way: pipe anything into it and get back a URL. Drop this into your
+`.zshrc` / `.bashrc` — a **function** is preferred over a plain alias because it
+reads stdin cleanly and has room to grow options (needs `jq` + `curl`):
+
+=== "Function (recommended)"
+
+    ```bash
+    # paste stdin to the rethink paste service, print the URL.  usage:  cat file | pb
+    pb() {
+        jq -Rns '{text: inputs, expires: 259200}' \
+          | curl -s -H 'Content-Type: application/json' --data-binary @- https://paste.rethinkstudios.io/ \
+          | jq -r '"https://paste.rethinkstudios.io" + .path'
+    }
+    ```
+
+=== "Alias (alternative)"
+
+    Same behaviour as a one-liner — note the extra escaping the alias form needs:
+
+    ```bash
+    alias pb="jq -Rns '{text: inputs, expires: 259200}' | curl -s -H 'Content-Type: application/json' --data-binary @- https://paste.rethinkstudios.io/ | jq -r '\"https://paste.rethinkstudios.io\" + .path'"
+    ```
+
+Usage — pipe any file or command output straight in:
+
+```bash
+cat latest.log | pb           # -> https://paste.rethinkstudios.io/xxxxxxx
+mycommand 2>&1 | pb           # pipe any command's output (stderr too)
+```
+
+`expires` is in **seconds** — `259200` = 72h (the default). Change it (e.g.
+`86400` for 24h) or drop the field entirely.
+
+!!! info "Rate-limited on creation"
+    The service rate-limits paste **creation** (not viewing), so it's built for
+    occasional shares — not bulk or automated posting.
