* fix(agents): gate WS text delta emission on valid phase value, not map key existence
When output_item.added arrives without phase metadata, outputItemPhaseById
stores undefined. The previous .has() check returned true for undefined
values, bypassing the buffering gate and leaking commentary as unphased
visible content.
Fix: change .has() to .get() !== undefined on both delta and done handlers.
Fixes#61477
* docs: note WS phase buffering fix (#61954) (thanks @100yenadmin)
* test(agents): cover phaseless WS output_text.done buffering (#61954)
* test(commands): fix session-store import path for tsgo (#61968)
