Update to odrcore 6.0.0

🤖 Generated with Claude Code

Pulls conan-odr-index up to 36caf08, which adds the odrcore/6 recipe, and moves the app onto odrcore 6.0.0.

6.0.0 drops the pdf2htmlEX and wvWare backends and reworks the HTTP server API, so the consumer side has to move with it.

Dropped backends

with_pdf2htmlEX and with_wvWare are gone from the recipe, and both were already False here. pdf2htmlex, poppler-data and fontconfig leave the dependency graph with them, which leaves the deployer branches that copied their data into the app bundle dead — odrcore's own data is all there is left to deploy.

Nothing in the app referenced those assets: PDFs are handed to WKWebView, not to odrcore.

bind() / listen()

HttpServer::listen(host, port) is split into bind() + listen(). bind() runs on the calling thread, reports a failed bind as ServerBindFailed instead of swallowing it, and returns the port it got. That removes the reason for every socket call CoreWrapper had:

• the bind test that checked the port was not already somebody else's
• the readiness probe that waited for listen() to bind on the server's own thread

Connections land in the backlog from bind() onwards, so there is nothing to wait for before handing URLs to the web view.

It also removes the reason for a fixed port. Binding port 0 asks for whichever one is free and bind() reports which that was, so the two flavors of the app can no longer collide on 29665 — the failure this API change was made for. The port lives in a global now, since isServedURL: and the page URLs both need it.

Net: −94 lines in CoreWrapper.mm.

Server cache

HttpServer::Config::cache_path and config() are gone, and clear() no longer deletes files. Nothing is lost — the pages were always translated into the cache path passed to html::translate, which is the system's temporary directory. The server's own cache directory was only ever used by the serve_file that 6.0.0 removed.

Tests

The port in testOnlyTheServersOwnURLsCountAsPages is derived from the served URL rather than hardcoded, with a bare-host case (http://127.0.0.1/…) added — a URL without a port no longer reads as "not ours" for free.

Verification

• conan/setup-all.sh — all 13 configurations resolve and build
• bundle exec fastlane tests — 27 passing, including testPagesAreServedOverLoopback and testTheWebViewLoadsAServedPage
• xcodebuild … -sdk iphoneos — ODR Full/Release and ODR Lite/Release Lite both build
