Symmetrical to 83a4606a9 which wired the compactor into mana-ai. Both
webapp consumers of runPlannerLoop (Companion chat engine, Mission
runner) now pass a compactor that folds the middle of messages into
a <compact-summary> when cumulative token usage hits 92% of
maxContextTokens.
COMPACT_MAX_CTX is a module constant — gemini-2.5-flash's 1M-token
ceiling — not env-wired. Vite builds for the browser and PUBLIC_*
flags are the wrong tool for a value that only matters to the loop
runtime; changing the model means changing the constant alongside the
model reference anyway.
Uses the same LlmClient + model as the planner's own calls. A cheaper
compactor-tier model (Haiku) is the optional M2.5 follow-up and does
not require changing this wiring — only the compactHistory `opts.model`
gets swapped.
Type-check clean (svelte-check 0 errors 0 warnings across 7389 files).
All 31 companion + mission tests green.
