chore(agents): roster sweep — arm discussion agents, integrate inigo, drop tiger (T-1104)

Cleared stale STANDBY markers, swept dead DISCUSSION.md pointers, disambiguated overlapping personas, corrected asset-gen paths. Armed 7 discussion agents (gestalt/gore/mellanie/miri/nigel/ozzie/paula) with Bash so they can run the pql preamble. Integrated inigo into the roster + briefing (audio, standby). Removed tiger — localization dropped from scope (R-013). Part of T-1099.
