opencode: dev/architect/review/duck/brainstorm on Muse Glimmer

Adds muse-glimmer-30b and muse-glimmer-30b-low to the local and personal
profiles, and points the five named agents at the -low alias.

-low, not the bare alias, because that is the configuration llmbench
actually measured: 15/24 tests_pass on the real suite at reasoning_strength
low, the best any local model has scored there. The bare alias runs at
Glimmer's default, which is its HIGHEST reasoning setting and cannot be
turned off -- measured 906 completion tokens for a one-line riddle against
360 at low. Both are declared, so switching is a model change, not an edit.

Context is 131072, from llama-swap's own `-c`.

These agents already exist in work.json/work-strict.json on gpt-5.6-terra
and are untouched there; local and personal had no agent block at all, so
this is additive.
