🪟 feat: Faithful Over-Window Context Estimate via Prune Mirror and Overhead Reserve (#13959)
*  feat: Mirror send-path pruning in the over-window context estimate

For a snapshot-less branch whose tokens exceed the window, the send path
prunes oldest-first (getMessagesWithinTokenLimit), so the next call can sit
well under the window. The gauge previously clamped the full sum to 100%,
hiding that headroom. Add prunedBranchTokens — a newest->oldest walk that
keeps messages until the next would overflow the message budget (max minus the
summary baseline), mirroring the pruner — and use it on the estimate path in
place of the clamp. Approximation: omits the instruction/tool overhead and
tool-call pairing the real pruner accounts for (unknowable for a snapshot-less
branch); superseded by an exact snapshot once the branch is generated.

*  feat: Reserve cached instruction/tool overhead in the snapshot-less estimate

The over-window prune mirror and the gauge couldn't account for the fixed
instruction + tool-schema overhead the next call always sends, because a
snapshot-less branch has no breakdown. The backend already emits that overhead
in the ON_CONTEXT_USAGE breakdown, so cache it per agent/model (keyed
endpoint::model::agentId, already inclusive of tool schemas) from the live
usage events, then reserve it from the prune budget and add it to used so the
estimate is consistent with snapshots. Falls back to message-only until the
agent has run once this session. Surfaced as a System row in the estimate
breakdown.

* 🩹 fix: Address Codex review on the over-window estimate

- Key the overhead cache by agentId when present. useTokenLimits resolves an
  agent to its real provider/model, so the reader keyed `provider::model::agent`
  while the writer stored `agents::::agent` — a cache miss for the main agents
  case. Both sides now resolve to `agent:<id>` (non-agent configs: endpoint:model).
- Skip the overhead reserve when a summary baseline exists: computeSummaryUsedTokens
  already folds instruction/tool overhead into that marker, so adding it again
  double-counted on summarized branches.
- Collapse the breakdown's input/output/estimated rows into one pruned Messages
  row when over-window pruning ran, so the popover matches the gauge instead of
  summing to the discarded pre-prune history.
