Harness spec 3.2.0: reasoning goes back during its turn; no absolute paths

context.md §8: every assistant message of the current turn (after the
last message that started a turn — a step-boundary delivery does not)
carries its reasoning back, as reasoning_content in OpenAI chat and as
thinking blocks in Anthropic; earlier turns carry none, which the common
templates render identically. §11: an agent session's prompt names no
absolute machine path: the environment block names the project and says
paths are relative to its root (loop.json context.env), files outside
the project under home as ~/…; relative paths resolve against the
project root, absolute ones still accepted. agents-missing.md and
init.md no longer name the root. New conformance areas: reasoning, paths.
