The tab strip was visible for everyone regardless of which tools they
actually run, which produced a row of All + one provider for Claude-only
users and a row of All + zeros for users on exotic stacks. Hide the
whole row until a second provider has real spend, matching the behavior
the GNOME extension ships with.
Also expand ProviderFilter to include every provider the CLI supports
(OpenCode and Pi were missing) so their tabs appear when those tools
produce sessions. The CLI already emits pi and opencode in the payload's
providers map; the Mac app just wasn't offering a tab for them.
visibleFilters now filters on value > 0 instead of key presence, because
the CLI includes zero-cost entries for discovered-but-unused providers
and we don't want those rendering as blank tabs.
Removes references to future signing decisions, dollar amounts, and
star thresholds from the menubar README, the CHANGELOG, the release
workflow (its YAML comments and the auto-generated release body), and
the packaging script. The technical description stays; the 'we are
not paying for X right now' framing is out.
Caught in a fresh-clone smoke test: SwiftPM refused to build because
.process("../../Resources") pointed at an empty directory that git
does not track. The bundle has no assets to ship yet (icon will land
with signing work), so the reference is gone. Build passes on a clean
checkout and the packaging script produces the universal .app zip as
expected.
