Rename 9harness to 9agents; README, file-backed qids, worded errors

- 9harness/ becomes 9agents/ (build option -D9agents, package paths).
- 9agents serves /README, reports qid paths from the file's (dev, ino)
  and qid versions that move with the file, and names its refusals.

-//! Build fragment for 9harness: the harness fs daemon (binary `9harness`),
-//! a read-only fresh-from-disk 9P2000 view of every harness's state,
-//! posted by default under the name `harness`. It is `@import`ed by the
-//! root build.zig and called with the root builder, so every `b.path(...)`
-//! here is relative to the cloud9 root (hence the `9harness/` prefix),
-//! every option is defined by the root and every step it registers lands
-//! in the root's step list under the `9harness` prefix.
-//!
-//! Steps: 9harness, 9harness-test, 9harness-itest.
