- Introduced `Max` as a first-class reasoning effort tier across all packages, including AI providers, coding agent configurations, and RPC protocols.
- Refactored model effort ladders to use wire-exact mappings and removed legacy effort aliasing (e.g., `max-to-xhigh` mapping).
- Updated model registry and provider configurations to support `Max` tier routing, color themes, and UI icon associations.
- Expanded test suites to provide end-to-end coverage for the new reasoning tier, including updated compatibility and fallback scenarios.
- Reduced shimmer-driven UI animations and borders to a 30fps cadence.
- Collapsed consecutive read tool calls into one finalized transcript block.
- Tracked visible assistant content to finalize and reset read groups correctly.
- Updated running task rows to static bullet markers with shimmer-only subagent labels.
The new `spinnerFrames` entry inside the `symbols` block was added without closing the surrounding `properties` object, so `JSON.parse` failed on the bundled schema with `Expected '}'`. Restore the missing `},` so editors and tooling that follow the `$schema` URL can validate custom themes again.
Refs #1553
Adds a `symbols.spinnerFrames` field to the custom theme JSON schema so themes can override the loader/tool-execution spinner that drives `theme.spinnerFrames` / `theme.getSpinnerFrames(type)`. Accepts either a flat `string[]` (used for both spinner types) or an object `{ status?, activity? }` to override each type independently; anything not specified falls back to the active symbol preset (unicode/nerd/ascii). The override is plumbed through `createTheme` and the `Theme` constructor, normalized via `normalizeSpinnerFramesOverride`, and read in `getSpinnerFrames`.
Mirrors the field in `theme-schema.json`, documents it in `docs/theme.md`, and adds a test covering flat-array, per-type, validation-rejection, and preset-fallback paths.
Fixes#1553
- Adopted draft-2020-12 tuple validation with `prefixItems`, rejecting array-valued `items`.
- Expanded strict-mode handling to recurse `prefixItems` entries and infer `array` when tuple prefixes exist.
- Normalized Anthropic schemas through `prefixItems`, keeping supported tuple constraints and dropping unsupported fields.
- Updated coding-agent schema metadata and tests to draft-2020-12 `$schema` targets, including MCP/theme fixtures.
- Added `trimTrailingWhitespace()` to strip trailing spaces/tabs and keep the original line when none exist.
