feat(toolsets): per-toolset config/env/provider/post-setup management (#782) (#831)

* feat(toolsets): per-toolset config/env/provider/post-setup management (#782)

* fix(toolsets): per-entry toolset name for shared detail ViewModel (#782)

NavDisplay uses the activity-level ViewModelStoreOwner, so class-keyed
viewModel{} returns the same ToolsetDetailViewModel for every detail
entry; the constructor-captured name froze the first-opened toolset into
all entries (on-device: every toolset showed web's providers, no further
/config calls after the first). The screen now drives setToolset(name) +
loadConfig() per entry, and setToolset resets per-toolset state
(config, revealed secrets, running post-setup) so nothing bleeds across
toolsets.

* style(toolsets): single-line scrollable tool chip strip (#782)

A wrapping FlowRow stacked chips vertically for toolsets with many
tools (web etc.), ballooning card height — especially on large font
scales. Chips now sit on one horizontally scrollable row.

* chore(toolsets): drop stray terminal-noise line from chip strip change
