Accept ctx as the first parameter on the blocking I/O entry points and
propagate it to downstream blocking calls so the work is cancellable from
the process entry point:
- appconfig.Load / LoadWithOptions: honor ctx before the blocking file
reads, returning defaults on a cancelled context.
- LSP: lsp.Server.Run(ctx) ties the serve loop to the caller context via a
new watchParentContext bridge (cancels the server context, aborting
in-flight LLM work). Threaded through hexailsp.Run/RunWithConfig/
RunWithFactory and runtimeconfig.Store.Reload.
- MCP: mcp.Server.Run(ctx) stops accepting requests once ctx is cancelled;
threaded through hexaimcp.Run/RunWithFactory/RunBackfill.
- editor: RunEditor/OpenTempAndEdit/OpenFile take ctx and use
exec.CommandContext so a cancelled context kills the editor subprocess;
threaded through hexaicli, hexaiaction and askcli call sites.
Top-level callers (cmd/hexai-lsp-server, cmd/hexai-mcp-server) now build a
signal-cancelled context (SIGINT/SIGTERM) so shutdown tears the run down
cleanly. Updated comments to explain the cancellation flow and added
cancellation tests for the LSP/MCP loops, editor, and config load.
All tests pass with -race; cross-package coverage 86.2%.
