Semlith Files

Docs, metadata and one workflow. The binary behaves as 0.46.0.

Added

• Listed in the official MCP registry. server.json names the server io.github.semlith/semlith, a cargo package run as semlith mcp over stdio, and the README carries the mcp-name line the registry checks on crates.io. tests/readme.rs fails when server.json's version and the crate's disagree.

Changed

• The README leads with what semlith changes for an agent. The first screen states the documents agent round (an Opus agent found 63 % of passages with Grep, Glob and Read and 98 % with semlith; 41 of 127 grep quotes were not in the document they named, 0 of 126 with semlith) beside the single-repo code result where it does not help (92 % either way). A recording of semlith search answering from a PDF and a Word file, rendered by vhs from docs/images/demo.tape, replaces the portal screenshot, which moves to The portal.
• Dependencies. libc 0.2.191, tree-sitter, tree-sitter-scala 0.26.3 and zip patch updates (Dependabot [#259]), with THIRD-PARTY-NOTICES regenerated for the scala grammar.

Fixed

• The clean-install workflow's Windows tamper check works again. It rewrites install.ps1's origin line wherever the script indents it; from 0.46.0 the line sits inside a script block, so the check failed in setup instead of testing a tampered release.
