ADFA-6692

Adds Build Animation, a plugin that puts an animated icon at the end of the editor toolbar while Gradle works: a wrench rocks during a build or sync, then a tick or a cross shows the result for 5 s. Idle, it is a greyed-out wrench. Our own vector art; no permissions.

How

• Uses the host's dynamic toolbar icon (ToolbarAction.iconProvider + IdeUIService.refreshToolbarActions()); the host starts animated drawables itself (ProjectActionsToolbar.kt:57 in CoGo). No custom view, overlay or inset handling.
• BuildAnimationState is a plain state machine behind a Scheduler seam, unit-tested on the JVM.
• Supports CoGo 26.29-26.99: 26.29 is the first release with iconProvider, refreshToolbarActions() and the host's auto-start of animated icons.

Design changes found on device

• Greyed out when idle, not hidden. The first version hid the icon when idle. On device, every built-in button shifted one slot when it appeared and jumped back when it hid: the toolbar is end-aligned, so Stop moved out from under the finger that had just tapped Run.
• 5 s result window, not 3 s. CoGo's own "Build successful" flashbar covers the toolbar for about 2 s (DURATION_SHORT) and hid most of a 3 s tick.

Verification

• assemblePlugin from a clean tree: no warnings; provenance revision_source=git, not dirty. testDebugUnitTest: 6/6. The new-build-during-result test fails without the cancel-on-start fix (expected:<BUILDING> but was:<IDLE>).
• addons check: 0 problems. Run from tools/addons/src on the system Python with jsonschema 4.10, not via uv.
• plugin-review: the first pass found 6.6 (missing required HTML sections), 6.1 (no max IDE version) and 6.2 (empty dispose()). All three are fixed in the second commit.
• On device (Galaxy Tab SM-X238U, debug CoGo C-d-0929-1057): install, idle greyed wrench, wrench animating during sync, tick on success, cross on cancel, and no button shift.

Not verified:

• Long-press tooltip: the tablet's documentation.db is empty (no such table: Tooltips), so no plugin can register tooltips there.
• Font scale 2.0: set mid-sync and the icon kept animating, but text didn't visibly grow, so it isn't a real 2.0 check. The icon has no text.
• Not run: a genuine compile failure (cancel exercises the same onBuildFailed path) and animations turned off.

Known limits

• A project sync reports to plugins as a build start, so it animates too.
• Quick Build does not notify plugins, so it doesn't animate (core follow-up).
• The plugin API carries no progress, so the animation is indeterminate.

Seen in passing, not changed here

• Speech-to-Text's toolbar tooltip probably renders n/a. The host looks up toolbar tooltips as <pluginId>.<actionId> (PluginToolbarActionItem.kt:81-82), but STT registers the bare stt_voice_to_code.
• Updating an installed plugin needs an uninstall. The update was refused with "installed from a different build variant" between two release builds of this plugin, so it had to be uninstalled first.
