* feat(diagnostics): report a byte entropy profile for one local file The diff adds the MCP tool inspect_byte_entropy and the CLI command inspect-byte-entropy, both implemented by ByteEntropyService. One absolute regular file is read offline into observed Evidence: file-wide SHA-256 and Shannon entropy, then fixed blocks and adjacent runs for an optional window, using a power-of-two block size from 256 to 65536 (default 4096), with high at 7.2 or above and low at 1.0 or below. A window past EOF, a missing path, or a non-file is an input error; a size or identity change during the read is an artifact-changed error; empty input reports entropy 0; cancellation is honored before and during the read. Summary detail retains the complete series and returns file entropy, counts, and the ten longest runs for inspect_analysis_view, while the registered effect remains read-only Evidence and the diagnostics docs record the operation and its errors. * fix(diagnostics): flag zero-size files as not shown empty Generated files such as Linux /proc entries report size 0 while holding content, so inspect_byte_entropy read nothing and returned an empty-looking report. A file that reports size 0 now carries a limitation that the result does not show the file is empty. The result stays a success because the tool reads the declared size, which the file-stability checks depend on. * fix(mcp): reject unsupported diagnostic summaries before inspection * fix(ci): repair integrated checks and Hopper test baseline * test(entropy): use shared MCP schema verification after merge
