Firenook 0.2.0-next.2

1. Firestore no longer reads the whole store to serve the Emulator UI and the listings it polls: ListCollectionIds, ListDocuments with missing documents or no collection id, recursive delete and clear-database walk keys under a prefix; an unfiltered count() reads only the scope index; REST runQuery honours select. Firestore reads run on a bounded read pool instead of the shared async workers, so a long scan no longer stalls Auth, Storage or the UI; Auth persists its state only when a request changed it; the Requests-diagnostics report is summarized once a minute.

2. Listen streams wake on a commit notifier instead of a 10 ms poll and maintain their views incrementally, falling back to full evaluation only for window exits and moves, offset, limit_to_last and nearest-neighbour queries.

3. Disk state keeps an equality index over every document's top-level fields: a query with == or in on them reads only the documents holding the value instead of its whole collection. Every filter is still evaluated on each candidate, so results are unchanged; ranges, or, !=, not-in, array membership, nested paths and collection groups still scan. A state last written by an earlier release rebuilds the index on its first start, in the pass that already reads every document (measured at 246 s for a 32.6 GB, 1.9-million-document state); FIRENOOK_FIELD_INDEXES=0 turns it off.

4. The emulator's own console is served under /console on the UI port, beside the Google Emulator UI, which stays the default. It is an early scaffold: overview, shell and command palette.

• Pin the engine to 63d554c15f2699cf623c7fac19a4d1393c77f322, the qualified head of PR #66 (the equality field index) on PR #67 (clippy on Rust 1.99), PR #63 (the console scaffold) and PR #62 (the read path). This exact revision passed CI (run 37119862089) and the five-platform packed-install matrix (run 37119862029); locally the workspace tests (51 suites), clippy, the packaging tests (92/92) and the Firestore conformance suite in memory and disk modes (37/37 each) passed, and a store written by it reopened on 0.2.0-next.1, was written there and reopened here with its field index rebuilt.
