diff-logs does not find the repo root and treats probe scripts in the repo as source #11

Summary

Two problems with diff-logs:

• (a) Run from a subdirectory it does not walk up to the repo root (openshell-annotate.toml).
• (b) A probe driver that lives inside the repo is scanned as source and --write inserts directives into it.

Steps to reproduce

(a) cd openshell && openshell-annotate diff-logs sandbox-logs.txt: only that directory is scanned, so it reports 0 stale directives and a wrong place: for suggestions.

(b) Keep the probe driver in the repo (openshell/exercise.sh, openshell/observed-egress.sh) and run diff-logs --write: a directive is inserted into those scripts.

Expected

• Walk up to the directory containing openshell-annotate.toml, like the other commands.
• Honour [scan].exclude, and add an [diff-logs] exclude, so probe scripts are not used as directive targets.

Actual

Wrong root, wrong placement, and directives written into probe scripts.

Found while testing five real projects (see the local candidate report). Numbered #5 in that report.
