filesystem.md, spec 3.0.0-draft, and the CLI made to match:
- Paths: absolute in every answer except a result's bracket (context.md),
which keeps the call's path. glob and grep now give full paths.
- A missing file is `No such file or directory: {path}` for every tool
that needs it, with no hint after it: in a chat a hidden file must read
as a missing one. The CLI's "does not exist. Use write to create it." and
"Write it first." are gone; an edit of a directory is `Is a directory`,
glob over a file `Not a directory`.
- write/edit refusals, exactly: "{path} exists and has not been read in
this session. Read it first." and "{path} changed since you last read
it. Read it again before changing it." (no "on disk"), absolute path.
- A listing sorts names in code-point order; `list` with a depth is a
tree indented two spaces a level, marks as in a single listing, cut at
400 lines with a line saying so.
- Skills: where they are found and in what order on each side (the
session's own place first, the person's next, what is shared last), and
the name rule ^[a-z0-9][a-z0-9-]{0,63}$ that skill_manage checks. The
CLI no longer makes names with _ or .; such skills still load.
README's 3.0.0 notes say so; CHANGELOG [Unreleased].
