- Fixed schema compatibility issue by sanitizing patternProperties in tool parameters during Antigravity format conversion.
- Added sanitizeSchemaForCCA utility to remove unsupported schema properties when rewriting tools to legacy parameters format.

- Added PEP 563 forward reference support to Python prelude for improved type annotation compatibility.
buildAnthropicSystemBlocks was unconditionally adding cache_control to system
blocks for OAuth cloaking. This triggered the early-return guard in
applyPromptCaching, which bailed before placing cache_control on conversation
messages. Result: only the system prompt (~21K tokens) was cached; conversation
history was sent as fresh uncached input every turn, dropping cache hit rate
from ~98% to ~40%.
Fix: make cache_control in buildAnthropicSystemBlocks opt-in via a cacheControl
option. The main streaming path (buildParams) omits it since applyPromptCaching
handles all cache breakpoint placement. External callers like the Anthropic
search provider that bypass applyPromptCaching pass cacheControl explicitly.
The guard in applyPromptCaching now only checks messages (for external callers
that pre-place breakpoints), not system/tool blocks.
Also removes dead hasCacheControlInBlocks function.
Introduced by: e7daffdda (feat: Claude fingerprint hardening)
Verified: cache hit rate restored from 20.8% to 99.3%.

PendingAction.apply() and reject() now receive the reason string that was
passed to resolve(). This lets custom tools surface the agent's rationale
in their apply/discard output or use it for logging.
- PendingAction interface: apply(reason) and reject?(reason)
- CustomToolPendingAction: same signatures, reject is optional
- CustomToolLoader: threads reject through when building PendingAction
- AstEditTool: accepts _reason (unused, reserved for future tracing)
- resolve.test: covers reason forwarding on apply and reject paths,
and verifies reject return value replaces the default discard message
- docs/resolve-tool-runtime.md: updated interface table, built-in
producer description, usage example, and developer guidance
- Introduce `deferrable?: boolean` on AgentTool, CustomTool, and ToolDefinition.
AstEditTool sets it to true; resolve is now injected only when at least one
active tool is deferrable (previously unconditional).
- Replace single-slot PendingActionStore (set/get/clear) with a LIFO stack
(push/peek/pop/clear). Multiple deferrable tools can stage independent
preview actions; resolve always consumes the topmost one first.
- Wire pendingActionStore through discoverAndLoadCustomTools / loadCustomTools /
CustomToolLoader so custom tools can call pushPendingAction(action) to
register a resolve-compatible pending action with label, apply callback,
optional details, and optional sourceToolName.
- Export HIDDEN_TOOLS and ResolveTool from the SDK for manual tool composition.
- Add CustomToolPendingAction type and pushPendingAction to CustomToolAPI.
- Update createAgentSession to re-inject or remove resolve after the deferrable
audit, consistent with createTools behavior.
- Add LIFO resolve test, update existing tests (set -> push, get -> peek).
- Add docs/resolve-tool-runtime.md covering PendingActionStore internals,
built-in producer example, and custom tool usage guide.
- Simplified resolve tool output rendering from boxed layout to inline highlighted format for cleaner display.
- Updated resolve tool to parse source tool name from label using colon separator instead of separate metadata field.
- Replaced CachedOutputBlock with direct line rendering using padToWidth and inverse styling.
- Removed actionBadge helper function and consolidated action/state logic into single rendering path.
- Updated 1 test to verify inline rendering behavior and label parsing.
