Cipherandgensokyo-dev 18a8e71c9f feat(artifacts): add U-Boot legacy uImage reader (part of #7129) (#7234)
* feat(artifacts): add U-Boot legacy uImage reader (part of #7129)

Recognize legacy uImages by their 0x27051956 magic and inventory them as containers: 64-byte header facts (arch/os/type/compression raw and named, load/entry addresses, name, timestamp) with header and data CRC32 verified, stored payload extractable as payload.bin, and multi-file images split from the stored size table into image-<n>.bin. Compressed payloads stay as stored; nothing is executed or decompressed. Wires the format through classification, the artifact reader dispatch, extraction, and the evidence/snapshot format vocabularies. Related to #7129 (uImage part only); HEX/SREC and FIT are out of scope.

* fix(uimage): preserve aligned component ranges and exact header facts

* fix(uimage): retain buffered members through consumption and cancellation

* fix(uimage): preserve active read and validation failure precedence

## Start with one command
```bash
npx rea-agents setup
```
Choose your agent, review the planned changes, and approve setup. Native binary
analysis can use an existing Hopper, Ghidra, or IDA installation; static
JavaScript analysis needs no native analysis engine.
For a first result from an extracted JavaScript application or ASAR:
```bash
npx -y rea-agents@latest analyze-javascript-application /absolute/path/to/app --json
```
See [installation and setup](./installation.md) for requirements and configuration.
For runtime instrumentation, see the [Frida guide](./frida-instrumentation.md).
