Add boundary globs, hotspot norm/bot signals, real preset filtering, …

[Eilodon]

…coverage hot-reload, and FTS5 memory recall

• Boundary rules now accept glob patterns (crates/*/src/indexer/**) alongside the existing prefix-style rules, via globset with a literal-prefix fallback on invalid syntax.
• Fitness report surfaces a note when Tier-0.5 languages dominate the function/method population, since they always report complexity 1 and can silently understate high_complexity_pct.
• Hotspots expose normalized churn/complexity shares and classify each file's git churn as human/mixed/bot_dominated/unknown, filtering bot-authored commits out of the signal.
• MCP preset filtering (orient/trace/edit/compound) now actually scopes tools/list and tools/call, not just the suggested_next hint — previously every preset still received rmcp's full unfiltered tool_box.
• Coverage data (lcov/cobertura/etc.) reloads live when the watcher sees the report file change, instead of staying frozen at server-startup content.
• Memory recall's fuzzy query moves from unranked SQL LIKE to an FTS5 virtual table with BM25 relevance ranking and a recency tie-break, synced via insert/update/delete triggers with a backfill migration for existing notes.
