docs(pm-dispatch): the single-writer set is what SINGLE_CLAIM_PATHS enumerates, said where the seat reads batch independence (#17089)

Two lines in the 候选与批次 block, paid in place at 812/812 and ≤120 B per line:
the declared single-writer set is the enumeration in SINGLE_CLAIM_PATHS, sharing
any other path between open PRs is ordinary concurrent work whose cost is one
merge resolution paid by whichever lands second, and batch independence is not
read off a package or a check's name.

Paid by three deletions in the same five lines: the `priority:p0` 可超 `batch`
clause that duplicated the line three below it verbatim; 读数带 UTC 写进认领, which
the UTC-reading rule earlier in the file already states for claims; and the
depth-table provenance of LOCK_DEPTH_HOLD, which now lives in the PR that landed
it (git history), per the file's own one-line-provenance charter.
