* feat: add Agent SDK support with USE_AGENT_SDK feature flag
Add a feature-flagged code path that uses the Agent SDK instead of
spawning the CLI as a subprocess. When USE_AGENT_SDK=true is set,
the new SDK path is used; otherwise, existing CLI behavior is unchanged.
Changes:
- Add parse-sdk-options.ts for parsing ClaudeOptions into SDK format
- Add run-claude-sdk.ts for SDK execution with query() function
- Update run-claude.ts with feature flag check at entry point
- Update update-comment-link.ts to handle both cost_usd and total_cost_usd
- Add @anthropic-ai/claude-agent-sdk dependency

* refactor: simplify SDK types by using @anthropic-ai/claude-agent-sdk types directly
- Remove duplicate SdkRunOptions and McpStdioServerConfig types
- Use SDK's Options and McpStdioServerConfig types directly
- Return { sdkOptions, showFullOutput, hasJsonSchema } from parseSdkOptions
- Remove unnecessary convertMcpServers function
- Net reduction of ~70 lines

* refactor: use extraArgs for claudeArgs pass-through to CLI
Simplify option parsing by converting claudeArgs to extraArgs record
and letting the SDK/CLI handle --mcp-config, --json-schema, etc.
- Remove extractJsonSchema and parseMcpConfigs functions
- Add parseClaudeArgsToExtraArgs for simple flag parsing
- CLI handles complex args like --mcp-config directly

* refactor: remove hardcoded permission bypass flags
The SDK path should match CLI path behavior - permissions are handled
by the CLI itself, not hardcoded in the action.

of runtime validation in tag mode
- Add explanatory comment in agent mode about why prompt file is needed

* refactor: implement discriminated unions for GitHub contexts
Split ParsedGitHubContext into entity-specific and automation contexts:
- ParsedGitHubContext: For entity events (issues/PRs) with required entityNumber and isPR
- AutomationContext: For workflow_dispatch/schedule events without entity fields
- GitHubContext: Union type for all contexts
This eliminates ~20 null checks throughout the codebase and provides better type safety.
Entity-specific code paths are now guaranteed to have the required fields.

* refactor: improve discriminated union implementation based on review feedback
- Use eventName checks instead of 'in' operator for more robust type guards

* feat: defer remote branch creation until first commit
- For commit signing: branches are created remotely by github-file-ops-server on first commit
- For non-signing: branches are created locally with 'git checkout -b' and pushed when needed
- Consolidated duplicate branch creation logic in github-file-ops-server into a shared helper function
- Claude is unaware of these implementation details and simply sees it's on the correct branch
- No branch links are shown in initial comments since branches don't exist remotely yet
* fix: prevent broken branch links in final comment update
- Check if branch exists remotely before adding branch link
- Only add branch links for branches that actually exist on GitHub
- Add test coverage for non-existent remote branches
- Fixes issue where users would see broken branch links for local-only branches
* fix: don't show branch name in comment header when branch doesn't exist remotely
- Only pass branchName to updateCommentBody when branchLink exists
- Prevents showing branch names for branches that only exist locally
- Add test to verify branch name is not shown when branch doesn't exist
* tmp
* feat: add use_commit_signing input with default false
- Add new input 'use_commit_signing' to action.yml (defaults to false)
- Separate comment update functionality into standalone github-comment-server.ts
- Update MCP server configuration to conditionally load servers based on signing preference
- When commit signing is disabled, use specific Bash git commands (e.g., Bash(git add:*))
- When commit signing is enabled, use github-file-ops-server for atomic commits with signing
- Always include github-comment-server for comment updates regardless of signing mode
- Update prompt generation to provide appropriate instructions based on signing preference
- Add comprehensive test coverage for new functionality
This change simplifies the default setup for users who don't need commit signing,
while maintaining the option to enable it for those who require GitHub's commit
signature verification.

* feat: use GitHub display name in Co-authored-by trailers
- Add name field to GitHubAuthor type
- Update GraphQL queries to fetch user display names
- Add triggerDisplayName to CommonFields type
- Extract display name from fetched GitHub data in prepareContext
- Update Co-authored-by trailer generation to use display name when available
This ensures consistency with GitHub's web interface behavior where
Co-authored-by trailers use the user's display name rather than username.

* fix: update GraphQL queries to handle Actor type correctly

* refactor: clarify Co-authored-by instructions in prompt
Replace interpolated values with clear references to XML tags and add

- Add clear formatting instructions and example
- Explain fallback behavior when display name is not available

* feat: fetch trigger user display name via dedicated GraphQL query
Instead of trying to extract the display name from existing data (which
was incomplete due to Actor type limitations), we now:
- Add a dedicated USER_QUERY to fetch user display names
- Pass the trigger username to fetchGitHubData
- Fetch the display name during data collection phase
- Simplify prepareContext to use the pre-fetched display name
This ensures we always get the correct display name for Co-authored-by
trailers, regardless of where the trigger came from.
