The Skills & Agents panel was always empty for OpenCode sessions even
when skills and subagents were used. buildAssistantCall (shared by the
OpenCode SQLite and file-based parsers, and Kilo Code) counted the
skill/task tool invocations but never read the skill name or subagent
type from the tool-call input, so the dedicated breakdowns had no names
to aggregate.
In OpenCode's part files the identifier lives in state.input: the skill
tool carries input.name and the task tool carries input.subagent_type.
Extract both in buildAssistantCall and surface them on
ParsedProviderCall.skills / .subagentTypes, then stop hard-coding
skills: [] in providerCallToTurn and providerCallToCachedCall so the
classifier's subCategory and the subagent breakdown receive the data.
Verified against real OpenCode data: the previously empty skills[] and
subagents[] now populate (pipeline-investigation, plan-spec, splunk, ...
and explore/general subagents).
Fixes#556

OpenCode 1.1+ stores sessions as file-based JSON under
storage/{session,message,part}/ instead of a SQLite DB, so the
SQLite-only provider discovered zero sessions on current installs and
reported no usage at all.
Add a file-based discovery and parser path, preferred when present and
falling back to the SQLite DB for pre-migration installs. Extract the
shared message-to-call logic (token extraction, tool and bash parsing,
cost) into session-message.ts so the file path, the SQLite path, and
Kilo Code stay identical.
