fix: address all Copilot review issues (PR #1, #2, #3)

[Sj295]

Summary

Addresses all Copilot review issues found across PR #1, #2, and #3.

PR #1 fixes (6 issues)

1. CronScheduler double onFire -- non-teammate tasks called onFire twice; fixed routing logic so teammate tasks go through onFireTask only, lead tasks go through onFire only
2. ForkedAgentRunner NPE -- runForked() logged parentHistory.size() before null check; moved size computation after null guard
3. FileChangedWatcher path matching -- matched events by filename only, ignoring directory; now matches on full normalized absolute path
4. PermissionDialog race condition -- concurrent tool calls could race on responseQueue and terminal rendering; added synchronized on resolve(); provideResponse() now clears queue before put() to prevent silent drops
5. CronTools agentId missing from schema -- agentId was read in call() but not declared in inputSchema(); added to properties
6. ClaudeCodeRequestAdvisor StringBuilder.isEmpty() -- verified compatible with Java 21 (no change needed)

PR #2 fixes (1 issue)

7. REPL mode tool exposure -- all enabled tools were registered as callbacks even in REPL mode, defeating the token-saving hiding behavior; now filters out REPL_ONLY_TOOLS when REPL mode is enabled

PR #3 fixes (5 issues)

8. AgentInvoker unused import -- removed java.util.function.Consumer import
9. permChecker treats Ask as allow -- PermissionResult.Ask was silently allowed, bypassing user confirmation; now returns a denial message
10. ToolCallbackAdapter Javadoc outdated -- updated to reflect that permission checks now happen inside the adapter
11. ToolCallbackAdapter null contextTemplate -- null contextTemplate could cause NPEs in tools; constructor now normalizes to ToolUseContext.defaultContext()
12. ToolCallbackAdapter log without stacktrace -- permission checker exceptions logged with e.getMessage() only; now passes exception object as last param for full stacktrace

Test Results

• 256 tests pass (no regressions)
