* fix: repair YAML bullet lists in malformed tool-call JSON (#2660)
When LLMs copy YAML template formatting into tool-call arguments, they
produce `"key": - item` instead of `"key": ["item"]`, causing JSON parse
errors that block milestone completion. Add a repairToolJson() utility
that detects and converts YAML-style bullet lists into JSON arrays before
parsing. Integrated into both the PartialMessageBuilder (claude-code-cli)
and the anthropic-shared streaming provider, with fallback in
parseStreamingJson for all other providers.

When the API stream is truncated mid-tool-call, PartialMessageBuilder
emits a toolcall_end event with { _raw: "<broken json>" } in the
arguments — but the event looks identical to a healthy tool completion.
Downstream consumers (error classifiers, tool handlers, activity log)
have no way to distinguish a truncated call from a completed one.
Add a malformedArguments: boolean flag to the toolcall_end event variant
in AssistantMessageEvent. The flag is set to true only in the JSON parse
catch path, so existing consumers (which do not check for it) are
unaffected. New consumers like classifyProviderError can use it to
handle truncated tool calls appropriately.
Closes#2574
Implements Phase 1 of the Claude Code subscription-as-provider integration
(issue #2509). Users with a Claude Code subscription (Pro/Max/Team) can
use subsidized inference through GSD's UI via the official Agent SDK.
The extension registers a provider with authMode: "externalCli" that
delegates to the user's locally-installed claude CLI. The SDK runs the
full agentic loop (multi-turn, tool execution) in one streamSimple call.
Tool calls stream in real-time for TUI visibility but are stripped from
the final AssistantMessage so the agent loop ends cleanly without local
tool dispatch.
Zero core changes — pure extension-based implementation.
Closes#2509
