feat(i1pro2): implement visual LED feedback in chartread (fixes #37)

- Add inst_led_state enum, INST_CAP_LED_STATUS capability, and set_led_state to inst.h / inst.c
- Implement i1pro2_indLEDset, worker thread i1pro2_led_thread, and i1pro_imp_set_led_state in i1pro_imp.c / i1pro_imp.h
- Wire up i1pro_set_led_state and determine_capabilities in i1pro.c for i1Pro 2 (Rev E)
- Integrate -Y l option and lifecycle hooks in chartread.c for calibration, readiness, success, failure, and clean exit

+Modifications in this fork:
+--------------------------
+Based on the upstream ArgyllCMS V3.5.0 release, this fork adds structured
+JSON output capabilities (via a common `-u` switch) to several tools so they
+can be driven as isolated subprocesses by external UIs while preserving
+AGPLv3 licence isolation (no library linking; communication over stdin /
+stdout / stderr only).
+
+Changes merged into main:
+
+- **chartread** (`-u`): Real-time row-level and patch-level colour
+  measurement events (`ROW_COLORS_JSON: ...`) containing device values,
+  measured / expected XYZ & D50 Lab, and optional spectral data.
+
+- **instlist**: New utility that enumerates connected instruments and emits
+  the result as structured JSON.
+
+- **printtarg** (`-u`): Emits a structured JSON target manifest describing
+  the generated chart.
+
+- **targen** (`-u`): Structured JSON progress output while generating test
+  chart values.
+
+- **profcheck** (`-u`): Structured JSON Delta E report.
+
+- **colprof** (`-u`): Structured JSON calculation / progress reporting
+  during profile creation.
+
+Supporting documentation for the chartread JSON stream protocol, payload
+schema, process lifecycle, and AGPL isolation guidelines is also included.

+# ArgyllCMS `chartread -u` Subprocess Integration Specification & License Isolation Guide
+
+This document specifies the communication protocol, JSON payload schema, process lifecycle, and licensing isolation architecture for integrating `chartread -u` into external user interfaces and control software.
+
+---
+
+## 1. Architectural & Licensing Boundary (AGPLv3 Isolation)
+
+ArgyllCMS is licensed under the **GNU Affero General Public License (AGPL) Version 3**. To ensure a separate host project (proprietary, MIT, Apache, etc.) is **not tainted** by the AGPLv3 copyleft terms, the integration must maintain a strict, arm's-length inter-process communication (IPC) boundary:
+
+### Core Isolation Rules
+1. **No Library Linking**: The host application **must never** statically or dynamically link (`#include`, `.so`, `.dylib`, `.dll`, `.a`) against any ArgyllCMS C libraries (`libinst`, `libicc`, `libcgats`, `libyajl`, etc.).
+2. **Subprocess Isolation via Standard OS Pipes**: `chartread` must run strictly as a standalone, decoupled child process.
+3. **Standard IPC Only**: Communication is conducted exclusively over standard POSIX / Win32 file descriptors (`stdin`, `stdout`, `stderr`).
+4. **Independent Binary Distribution**: The `chartread` binary should be treated as an external utility tool invoked by the OS shell or process manager.

+## 2. Command Invocation
+
+### Command Syntax
+```bash
+chartread [options] -u <target_basename>
+```
+
+* **`-u` Flag**: Enables real-time emission of JSON records to `stdout`.
+* `<target_basename>`: The base name of the input `.ti2` target file and output `.ti3` measurement file (without extension).
+
+### Key Command Options
+| Flag | Description |
+| :--- | :--- |
+| `-u` | **Required for streaming**: Emits `ROW_COLORS_JSON: ...` payloads on `stdout`. |
+| `-p` | Patch-by-patch spot mode (emits JSON after each individual patch). |
+| `-n` | Disable spectral readings (omits `spectral` field from JSON). |
+| `-c <port>` | Select communication port / instrument index. |
+| `-d` | Display measurement mode. |
+| `-t` | Transmission measurement mode. |
+| `-e` | Emissive measurement mode. |
+
+---
+
+## 3. Stream Protocol & Framing Specification
+
+When `-u` is provided, `chartread` outputs two types of lines to `stdout`:
+
+1. **Human-Readable Status / Prompt Lines**: Unprefixed text intended for user prompts or diagnostics (e.g. `Hit [Space] to read strip A`).
+2. **Structured JSON Events**: Single-line JSON objects strictly prefixed by the marker:
+   ```
+   ROW_COLORS_JSON: <json_object>\n
+   ```
+
+### Stream Guarantees
+* **Line-Delimited**: Every JSON event is serialized as a single, uninterrupted line terminated with `\n`.
+* **Immediate Flush**: `chartread` explicitly invokes `fflush(stdout)` immediately after emitting each JSON line, guaranteeing low latency without OS-level output buffering.
+* **Deterministic Ordering**: Patches within a row are always indexed in canonical left-to-right strip order (bi-directional scan reversals are normalized internally before emission).
+

+
+### Top-Level Object Schema
+

+ROW_COLORS_JSON: {
+  "event": "row_complete",

+  "total_rows": 12,
+  "patch_count": 21,
+  "patches": [
+    /* Array of Patch Objects */
+  ]
+}
+```
+
+| Field | Type | Description |
+| :--- | :--- | :--- |
+| `event` | `string` | Event identifier. Currently always `"row_complete"`. |
+| `row_id` | `string` | Human-readable label of the row/strip (e.g. `"A"`, `"B"`, `"1"`). |
+| `row_index` | `integer` | 0-based index of the row within the target chart (`0 ... total_rows - 1`). |
+| `total_rows` | `integer` | Total number of rows/passes defined in the target chart. |
+| `patch_count`| `integer` | Number of patch elements contained in this row payload. |
+| `patches` | `array` | List of individual patch data objects. |
+

+  }
+}
+```
+
+| Field | Type | Description |
+| :--- | :--- | :--- |
+| `id` | `string` | Patch ID string from `.ti2` file. If `"0"`, indicates a spacer/padding patch. |
+| `loc` | `string` | Physical location coordinate string (e.g. `"A1"`, `"B12"`). |
+| `is_pad` | `boolean` | `true` if patch is an alignment/lead-in spacer patch (`id == "0"`). UIs should typically render these distinctly or skip them in analysis. |
+| `device` | `array[float]` | Device colorant drive values scaled to percentage `0.0 ... 100.0%` (e.g. `[C, M, Y, K]` or `[R, G, B]`). |
+| `expected` | `object` *(optional)* | Expected reference values from `.ti2` (omitted if no reference data is present). |
+| `expected.XYZ` | `array[float][3]` | Reference CIE XYZ values on reference scale `0.0 ... 100.0`. |
+| `expected.Lab` | `array[float][3]` | Reference D50 $L^*a^*b^*$ computed via standard CIE transformation. |
+| `measured` | `object` | Actual instrument readings. |
+| `measured.XYZ` | `array[float][3]` | Measured CIE XYZ values on reference scale `0.0 ... 100.0`. |
+| `measured.Lab` | `array[float][3]` | Measured D50 $L^*a^*b^*$ ($L^* \in [0, 100]$, $a^*, b^* \in [-128, 127]$). |
+| `measured.spectral` | `object` *(optional)* | Spectral reflection/emission data (omitted if instrument is colorimeter-only or `-n` passed). |
+| `measured.spectral.bands` | `integer` | Number of spectral sample bands. |
+| `measured.spectral.start_nm` | `float` | Starting wavelength in nanometres (e.g. `380.0` or `400.0`). |
+| `measured.spectral.end_nm` | `float` | Ending wavelength in nanometres (e.g. `700.0` or `730.0`). |
+| `measured.spectral.norm` | `float` | Normalization scale factor (typically `100.0`). |
+| `measured.spectral.values` | `array[float]` | Array of spectral reflectance / radiance values per band. |

+## 6. Real-Time UI Visualisation Best Practices
+
+1. **Rendering Device Colors**:
+   * For RGB targets: scale `device[0..2]` from $0..100$ to $0..255$ (`rgb(r%, g%, b%)`).
+   * For CMYK targets: use device simulation or convert `measured.Lab` / `expected.Lab` to sRGB for color swatch display.
+2. **Delta E Calculation ($\Delta E_{00}$ or $\Delta E_{ab}$)**:
+   * When `expected.Lab` and `measured.Lab` are both present, calculate the color difference $\Delta E$.
+   * The basic Euclidean distance ($\Delta E_{ab}$) is simple to implement directly:
+     $$\Delta E_{ab} = \sqrt{(L_m^* - L_e^*)^2 + (a_m^* - a_e^*)^2 + (b_m^* - b_e^*)^2}$$
+   * **Recommendation**: For professional color work, use the modern $\Delta E_{00}$ (CIEDE2000) formula. Due to its complexity, it is highly recommended to use an established color math library (e.g., `colorjs.io` in JavaScript, or `colormath` in Python) rather than implementing it from scratch.
+   * Display green/amber/red indicator lights next to each patch in real-time based on your accepted $\Delta E$ tolerance.
+3. **Handling Alignment / Spacer Patches (`is_pad == true`)**:
+   * Omit `is_pad == true` patches from quality score computations, or render them with dashed neutral borders to maintain layout grid accuracy without skewing statistics.
