Harness spec 3.2.0 in the CLI: effort levels, reasoning round-trip, no absolute paths

Levels (models/schema.json levels): provider/effort.ts levelsOf/levelFields/
readLevel — `off` only with thinking_switch and sends enable_thinking false
and no effort, `default` for a model that takes no efforts and sends
nothing, a level not offered is read as the start level. The engine's
effort is a level; /effort shows nothing for one level, a Thinking switch
for [off, X], a list otherwise; the status bar follows. /v1/models'
thinking_switch, efforts [] and capacity.parallel are read
(lembas/webui.ts); session/capacity.ts counts parallel slots.

Reasoning (context.md §8): an assistant message of the current turn
carries reasoning_content (provider/common.ts turnReasoning,
openai-chat.ts); step-boundary deliveries, nudges and the wrap-up are
marked turn: false and do not start a turn.

Paths (context.md §11): the <env> block names the project and, started
below the root, that directory relative to it (assemble.ts envLines);
instruction files and @ attachments are named from the root or as ~/…;
file tools and bash resolve relative paths against the project root.

The team rules (team/team.ts) and conformance runners for levels,
reasoning, paths and team; the team runtime follows.
