cctop 0.13.0

//! What an agent can reach: its instructions, skills, MCP servers and rules.
//!
//! A session's cost and its tool log say what it *did*. This says what it was
//! allowed to do and what was in scope while it did it — the CLAUDE.md it was
//! given, the skills on its path, the MCP servers wired into it, whether it asks
//! before writing, and whether cctop's own hooks are installed to hear about any
//! of it. Two questions people actually ask are answered only by this: "why did
//! it do that" (usually an instruction file nobody remembered was there) and
//! "what can it touch" (usually more than expected).
//!
//! # Why the data and the drawing are separate
//!
//! The terminal has shown most of this for a long time, in
//! [`crate::ui::panels`], as styled lines built straight from the filesystem.
//! A browser cannot use styled lines, and re-reading the same files a second
//! way is how two surfaces come to disagree about which MCP servers exist. So
//! the readers live here and return values; the panel renders them, and so does
//! [`crate::serve`].
//!
//! # It reports the files, not the truth
//!
//! Every harness resolves its own configuration, and none of them document the
//! whole of it. A settings file may be overridden by a flag on the command line,
//! an MCP server may have failed to start, a skill directory may hold something
//! the harness rejected. So this is deliberately phrased as "these are the files
//! that apply to a session in this directory", which is checkable, rather than
//! "this is what the agent has loaded", which is not. Where a harness keeps a
//! setting somewhere cctop cannot read — Windsurf's global rules live in the
//! editor's own settings UI — the entry says so instead of reporting nothing.
