feat(doc-syncer): PATCHED_FILES newline output for doc-commit handoff

doc-syncer now emits PATCHED_FILES — every public-doc file created/modified this run, ONE PATH PER LINE — in both STEP 9 OUTPUT (full audit) and AUTO MODE STEP A4 (the path orchestrators call). NONE stays silent (no line → doc-commit sees empty → no-ops). Additive: detection/patching logic and the `auto-mode scope:` input contract are unchanged → callers unaffected.

Separator contract, producer↔consumer aligned + proven: newline is doc-syncer's OUTPUT format (paths carry no newlines); the agent splits on newline and passes EACH path as a SEPARATE argv element to lib/doc-commit.sh. The helper takes argv (no in-band separator) → a path with spaces survives as one argument. lib/doc-commit.md spells this out (never flatten to a space-joined string + re-split, which would mis-split a spaced path the helper then silently drops). New test T7 PROVES it on real git: 'docs/My Guide.md' → committed as one file (28/28, shellcheck clean).

`PATCHED_FILES` is the machine-readable handle the doc-commit step (`lib/doc-commit.md`)
consumes — every public-doc file created or modified this run, ONE PATH PER LINE. Each line
is passed as a SEPARATE argument to `lib/doc-commit.sh` (newline split, space-safe). It NEVER
lists `.claude/**` or `CLAUDE.md` (never targets, BDR-022). Empty / `(none)` → doc-commit no-ops.

SEPARATOR — the helper takes argv (no in-band separator), so a path with spaces
(`docs/My Guide.md`) survives as ONE argument and commits correctly (proven, T7). NEVER
flatten the list into a single space-joined string and re-split it: that mis-splits a
spaced path into garbage args, which the helper's `[ -e ]` filter then silently drops —
the spaced doc would strand. Newline is doc-syncer's OUTPUT format (paths carry no
newlines); argv is the handoff to the helper.
4. REPORT BY (rc, doc_hash) — handle EVERY exit, not just success:
| rc | doc_hash | meaning | what to do |
