v1.1.0: native diff card client, 200-line paging for read/grep/glob, guard rule against shell edits/reads/searches

 A tag that was never issued for that file (e.g. copied from another file) is rejected with a hint.
 
+## Paging: read, grep and glob
+
+Like oh-my-pi, outputs are cut into pages so the model never pulls a whole file or huge search into context at once:
+- **`read`**: at most **200 lines** per call (`limit` above 200 is capped); the footer gives the `offset` to continue.
+- **`grep`**: at most **200 matches** per call, grouped under `[PATH#TAG]` headers. Pass `offset` for the next page (`… call grep again with offset=200`).
+- **`glob`**: at most **200 paths** per call, with the same `offset` cursor.
+
+Change the page size with `pageLines`.
+
+## Guard rule
+
+A `tools/pre-execute` listener makes the agent use these tools instead of working around them through the shell. Denied calls get a short reason that names the right tool.
+
+| Denied | Use instead |
+| --- | --- |
+| `sed -i`, `perl -i`, `ed`/`ex`, `tee`, `>`/`>>` into files, heredocs, `truncate`/`dd`, `python -c`/`node -e`… | `edit` (hashline) |
+| `cat`/`head`/`tail`/`less`/`bat`/`nl FILE`, `sed -n`, `awk` | `read` (paged) |
+| `grep`/`rg`/`ag`/`ack` over files | `grep` (paged, tagged) |
+| `find`/`fd`/`locate`, `ls -R` | `glob` |
+| `str_replace_editor`, `apply_patch` tools; `write` on an **existing** file | `edit` (`write` stays allowed for brand-new files) |
+
+What stays allowed:
+- Text inside quotes is ignored (`git commit -m "fix > bug"`).
+- Redirection to `/dev/null` is fine.
+- Filters on piped output keep working (`npm test 2>&1 | tail -5`, `ps aux | grep node`).
+
+If the guard can't check whether a path exists, `write` is denied rather than allowed (it fails closed).
+
+Turn the guard off with `guard: false`, or change the list of blocked tools with `guardTools`.
+
+## Diff cards in the Web UI
+
+The plugin ships a web client (`client.js`) that registers an `edit` tool view. Hashline, sloppy and apply_patch calls then render as DSH's native green/red diff card (from the applied hunks in `meta.diffs`), with `+N -M` counts, instead of raw patch text.
