docs(privacy): no private path and no coordination id in what this span added

A public repository should not carry the layout of the machine it was written
on, and it should not carry the identifiers of a queue nobody outside can see.
Six places in material this span added or changed did.

Neutral text, same facts: a private queue path in the EOL report, a private
note path in two docstrings and one report header, and four order identifiers
opening four reports. Where a sentence lost its source it says `internal
measurement note` -- the measurement is still named, the path is not.

One of them was output, not prose: row 9 of the retrieval gate printed a
`~/corpora/...` path to stdout on every run. It says the bundles exist on the
machine the row was written against; the row already takes `--k2 SET SHA
BUNDLE` from anyone who holds them.

Measured with the patterns as given, and both validated against a
known-positive on `df5a118` first -- an unvalidated pattern reporting zero is
not a measurement:

* `~/\.claude|/Users/|coord/.*/orders` over the 74 files the span touches:
  **9 -> 6**. The six left are deliberate: two README lines telling a reader to
  install a skill into their OWN `~/.claude/skills`, one prose line arguing
  that `/Users/...` is not more portable than a relative path, and three lines
  of `tests/test_retrieval_gate.py`'s own known-positive for this exact check,
  which removing would disarm it.
* `[0-9]{8}T[0-9]{6}Z-[0-9]+` over the 38 files the span ADDED: **4 -> 0**.

A note on the method, because the first run of the first grep reported 0 and
was wrong: zsh does not word-split an unquoted parameter, so
`git grep -- $FILES` passed 74 names as one argument and matched no file at
all. Both numbers above come from `$(git diff --name-only ...)`, which zsh does
split, and the known-positive is what made the false zero visible.
