A changelog for each service: ipx, the page, the directory

CHANGELOG.md moves to crates/ipx/CHANGELOG.md with its history, which until 0.12.0 was all of
ipx's; web/CHANGELOG.md and crates/directory/CHANGELOG.md start with this release's lines for the
page and the directory. The dashboard's lines go: monitoring is not a service anyone uses.
CLAUDE.md says which file a change goes in, and that a release covers each.

+# Changelog: ipx-web
+
+The page, and the container that serves it (Caddy). ipx's changelog is
+[crates/ipx/CHANGELOG.md](../crates/ipx/CHANGELOG.md), which was the page's too until 0.12.0, and the
+directory's [crates/directory/CHANGELOG.md](../crates/directory/CHANGELOG.md).
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Added
+
+- The page is served by its own container, ipx-web (Caddy), which passes the API to ipx on the same address, so a change to the page deploys without rebuilding ipx (#203).
+- Admin, Directory sets the directory's address and this server's token, and whether to share, and says how the last share went (#205).
+- A feed's settings have a Private switch, which keeps it out of the directory; on and locked for a feed whose address or login shows it is private (#205).
+- ipx-web logs one line a request, without the request's headers or a sign-in token in the address (#210).
+- ipx-web sends a trace span for each request when `WEB_TRACING=on`, continuing the page's trace into ipx (#213).
+
+### Changed
+
+- The Directory says when no directory is set up, and its counts are of everyone on every sharing server (#205).
+- Add a feed no longer asks for a folder; a feed's folder is its title (#201).
+
+### Fixed
+
+- On a phone, the Subscribe button on a Directory feed's page is full size again, not squashed to a sliver (#212).
