Eight commits since v0.3.0, which caselit, raglit and corrallm have all been pinned behind. dun tracks a local replace and has been on HEAD throughout.

Features

• mcpmgr delivers server→client notifications
• llm counts tokens exactly where the endpoint reports them, instead of estimating
• llm reports retry decisions and carries rich 429 backpressure detail

Fixes

• identical retry sleeps marched concurrent callers back in together
• the context probe aborted on the one refusal shape worth measuring
• agent persists the assistant reply on the session clock
• an unset shaper budget means UNBUDGETED, not a budget of zero
• mcpmgr carries a spawned server's stderr into the spawn error

No breaking changes — no exported function or type removed since v0.3.0. Verified by building caselit, raglit and corrallm against HEAD; caselit's full suite passes.

Breaking: Turn now returns TurnResult{Reply, Compactions, Usage} instead of (string, error).

• Cache-aware shaping — ShaperPolicy.LODHeadroomTokens (default ~10k): the Shaper reshapes when the context would cross BudgetTokens − headroom, not at the hard limit, so a restructure leaves runway and the prompt prefix (KV cache) isn't re-invalidated every turn. LOD first, compaction only if LOD can't fit.
• Compaction surfacing — CompactionInfo (summary + before/after tokens) via TurnResult.Compactions and the OnCompaction callback; the same turn continues to the reply.
• Token accounting — TurnResult.Usage / OnUsage: Total billed this session vs Active (current compacted window).
