fix: context pressure warning fires at 85% of context_length, not threshold

The _emit_context_pressure warning was firing at 85% of threshold_tokens
(the configurable compaction threshold), not 85% of context_length.
This caused it to fire at 42.5% of actual context when threshold_percent=0.50,
confusing users who expected alignment with the poka-yoke WARNING signal.

Fix: compare against context_length (0.85 * context_length) instead of
threshold_tokens. The compaction_progress passed to _emit_context_pressure
still uses threshold_tokens for the display bar, but the trigger condition
now matches the poka-yoke signal.

Closes #538
