Cut non-essential prose from docs and comments, and require the same of every future change

README loses the competitor comparison, the personas and the repeated philosophy; the
five near-identical E2E command blocks become a table plus one command, and the file
map a clause per entry. AGENTS.md keeps every decision but drops the narrative around
them. todo.md's completed items collapse to their task line — git holds the rest.

Comments lose restatement, README duplication and history ("used to", "originally",
dated notes). AGENTS.md gains a Prose discipline section making this a standing pass on
every change rather than a one-off cleanup.

src/compose.test.ts now expects 6 documented E2E run commands, not 10, since the README
states the command once instead of per suite.
