docs(changelog): a runner has a page of its own, and every list pages by cursor

[indykish]

Companion docs for agentsfleet/agentsfleet#577 (M146_001).

The Jul 30 <Update> covers the runner surface and the pagination retirement: the two new operator reads with their scopes, envelopes and error codes; the three reads that drop page/page_size; the fleets cursor rename; the memory envelope change; the retired client flags with their replacements; and the two additive index migrations. Upgrading leads, since client and server move together on all four breaks.

memory.mdx gains the new --starting-after flag beside the existing list example, and states that the dashboard panel walks the cursor to the end so it shows every entry.

make lint passes (its DOC-03 paragraph check caught a four-sentence paragraph, since split).

Land alongside or just after the product PR — the flags and envelopes documented here only exist once that merges and deploys.
