System prompt carries the contract; structure and reads go on-demand

SLA prompt section no longer embeds skeleton outlines (up to 8 x 4k
chars of per-document state as standing prompt weight): it now carries
only the always-on contract plus a one-line-per-document inventory
(name, ~tokens, handle count), and the model fetches outlines when it
reaches for a document via the existing library_outline tool.

Reading gains the compositional glue coding agents get from grep's
file:line: library_find hits now carry their original-text offset
(`at`) and deepest enclosing structural handle (`section`), and
library_read accepts offset/max_chars windows for text without numbered
structure - so the follow-up to a hit is a section read or a bounded
window, not the 300k-char whole-document default. That default is
unchanged pending an A/B (pilot-04 showed breadth-extraction tasks can
lose recall under forced-lean reading).
