Bug 1 — Output truncation:
_run_claude() was replacing raw stdout with parsed sub-field which
could be a dict (not string). run_agent() then saved dict.__repr__
to DB instead of full JSON. Fixed: _run_claude() always returns
string output; run_agent() ensures string before DB write.
Added tests: full_output_saved_to_db, dict_output_saved_as_json_string.
Bug 2 — Language support:
Added projects.language column (TEXT DEFAULT 'ru').
Auto-migration for existing DBs (ALTER TABLE ADD COLUMN).
context_builder passes language in project context.
format_prompt() appends "## Language\nALWAYS respond in {language}"
at the end of every prompt.
CLI: kin project add --language ru (default: ru).
Tests: language in prompt for ru/en, project creation, context.
112 tests, all passing. ~/.kin/kin.db migrated (vdol: language=ru).
