build(rawcli): make prompt_toolkit a core dependency + document rawcli

`pm3py rawcli` is a headline tool, so prompt_toolkit moves from the
[rawcli] extra into core dependencies — a plain `pip install` gets it and
the command just works. The extra is removed; the missing-module guard now
points at a reinstall (it only fires on a broken env).

README: add the rawcli feature bullet, a dedicated "pm3py rawcli"
section (breadcrumb, entry toggle, identify, function-style commands, live
trace, TLV, completion), prompt_toolkit in the dependency list, and cli/
in the architecture tree.

+## `pm3py rawcli` — interactive raw-command console
+
+`pm3py rawcli` opens an interactive, Proxmark-style console for driving a connected device at the
+raw level — a live annotated trace, flexible hex/binary entry, and function-style transponder
+commands. It's a **separate tool from the Python REPL**: its own command grammar, not Python.
+
+```bash
+pm3py rawcli                     # auto-detect the device (runs offline if none attached)
+```
+
+```text
+[raw / 0x] identify                    # probe the field; sets HF/LF + transponder, keeps the link
+NTAG213  (HF / 14a)  UID 04A1B2C3
+
+[raw / hf / NTAG213 / 0x] READ(4)      # function-style command from the tag's catalog
+[Rdr] Reader → Tag:  30 04          READ page 4
+[Rdr] Tag → Reader:  01 02 03 04 …
+
+[raw / hf / NTAG213 / 0x] 30 04        # …or send raw bytes directly
+[raw / hf / NTAG213 / 0x] tlv 00 03 09 D1 01 05 54 02 65 6E 48 69 FE   # decode a TLV / NDEF block
+```
+
+- **Breadcrumb prompt** `[raw / hf|lf / <transponder> / 0x|0b]` reflects the field, the identified
+  tag, and the current numeric entry mode.
+- **Entry modes** — type hex (`30 04`) or binary; **Ctrl-/** toggles `0x`/`0b`, digits auto-group
+  into bytes, and `0x`/`0b` prefixes can be intermixed on one line.
+- **`identify`** probes 14a → 15693 → LF and keeps the tag selected; **`transponder`** / **`close`**
+  manage the connection.
+- **Function-style commands** — `READ(4)`, `GET_VERSION()`, `WRITE(4, 0x01020304)` from the
+  identified tag's catalog (Type 2 / MIFARE Classic / ISO 15693 seeded). `help` lists them,
+  `help READ` shows one.
+- **Live annotated trace** — every exchange prints the reader↔tag frames with decoded annotations.
+- **TLV / NDEF** — `tlv <hex>` prints a structured multi-line breakdown; a multi-line editor
+  composes long TLVs.
+- **ipython-style completion** — command/argument menus with each command's help as the tooltip,
+  plus history auto-suggestion.
