Address review feedback: the routed-agent /clear path bypassed the
public ContextManager.Clear contract via an unexported hook. Restore
the single Clear call in the command path and resolve the session's
owning agent inside the built-in implementations instead:
- legacy: Clear resolves the owning agent via agentForSession instead
of assuming the default agent
- seahorse: drop ClearContextStore; Clear wipes the engine state and
the owning agent's session store
- command path: persist session scope metadata before Clear so
ownership resolves even when /clear is the session's first message
- add coverage that a custom ContextManager receives Clear for routed
agents

Address remaining review feedback: 1) Add HistoryTokens field to ContextUsage/ContextStats, showing history-only token count in /context and frontend UI alongside SummarizeAtTokens so users can see the actual summarization trigger comparison. 2) Remove .codebuddy/github-contribute/ state files accidentally included in the PR.
The /context command previously showed only the hard budget compression
threshold (contextWindow - maxTokens), which confused users who expected
to see the soft summarization trigger from summarize_token_percent.
This commit adds SummarizeAtTokens alongside the existing CompressAtTokens
so that both thresholds are visible:
- Compress at: contextWindow - maxTokens (hard budget, triggers proactive
compression when exceeded)
- Summarize at: contextWindow * summarizeTokenPercent / 100 (soft trigger,
matches maybeSummarize's threshold)
The fix updates the /context command output, the Web UI popover, and the
pico channel WebSocket payload.
Fixes#2968
Add a context window usage indicator to the web chat UI and a /context
slash command that works across all channels.
Backend:
- Add computeContextUsage() estimating history + system + tool tokens
- Attach ContextUsage to outbound messages via the pico WebSocket protocol
- Add /context command showing context stats as formatted text
- Add EstimateSystemTokens() on ContextBuilder for system prompt estimation
Frontend:
- Add ContextUsageRing component (SVG ring + hover/tap popover)
- Show usage percentage, token counts, and compression threshold
- Hover on desktop (150ms leave delay), tap on mobile
- "View Details" sends /context with 1s cooldown
- i18n support (en/zh) for popover labels
