Add snapshot.sh — dump all reports as clean text for LLMs and automation

- Runs all safe reports non-interactively, outputs clean plain text
- Strips ANSI colors, psql noise, DO/SET lines, NOTICE: prefixes
- Skips: interactive (r1/r2), expensive (b3/b4/c2-c4/m1), progress (p1)
- --full flag includes expensive reports
- Works with any psql connection args or connection string
- ~1500 lines / ~430KB for a typical database — fits in LLM context

 Works with the `pg_monitor` role — superuser is not required for most reports (corruption checks need superuser or explicit `GRANT EXECUTE`).
 
+## Snapshot Mode (for LLMs, scripts, automation)
+
+Dump all safe reports as plain text — perfect for feeding to an LLM, saving to a file, or piping into other tools:
+
+```bash
+./snapshot.sh -h localhost -U postgres -d mydb           # plain text output
+./snapshot.sh -d mydb > snapshot.txt                     # save to file
+./snapshot.sh -d mydb | pbcopy                           # clipboard (macOS)
+./snapshot.sh --full -d mydb                             # include expensive reports
+```
+
+Skips interactive and expensive reports by default. Use `--full` to include everything except interactive prompts.
+
 ## Adding Custom Reports
 
 Drop a `.sql` file in `sql/`. The filename format is `<id>_<name>.sql`. The first line must be a `--` comment with the description — it becomes the menu entry automatically.

+### snapshot.sh — LLM-friendly output
+
+New `snapshot.sh` script dumps all safe reports as clean plain text — no ANSI colors, no interactive prompts, no psql noise. Perfect for:
+- Feeding database state to an LLM for analysis
+- Automated health checks in scripts
+- Saving periodic snapshots to files
+
+```bash
+./snapshot.sh -d mydb > snapshot.txt
+./snapshot.sh --full -d mydb    # include expensive reports too
+```

 What's in your `shared_buffers` right now. Shows cached size vs total size, % of cache used per object, and dirty buffer counts. Requires `pg_buffercache` extension.
