fix: hide dashboard result preview for unsupported queries (Flotilla) (#6557) ## Summary The results preview tab was added to the dashboard in #6327 but only supports Swordfish queries since Flotilla never calls `on_result_out`. This hides the tab for Flotilla queries (rather than misleadingly displaying a disabled tab which will never become enabled) until we add support for them (follow-up: #6559). Note: for a while running Flotilla queries would actually panic the dashboard server process in `RecordBatch::from_ipc_stream`, but this was coincidentally fixed on main by #6541. This PR addresses the remaining issues: avoiding the empty serialization in the first place, and hiding the broken UI. ## Test plan - [x] `cargo check` passes for `daft-context`, `daft-dashboard` - [x] `tsc --noEmit` passes for dashboard frontend - [x] Manual: run a Flotilla query and verify dashboard doesn't panic, Results tab is hidden - [x] Manual: run a Swordfish query and verify Results tab still works --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

feat(subscriber): add Event enum and on_event dispatch for subscriber (#6508) ## Changes Made Introduces Event transport enum with OperatorStart/OperatorEnd/Stats variants and a single on_event async method on the Subscriber trait. Ports RuntimeStatsManager to emit all events through on_event, replacing direct per-method calls. Updates dashboard, debug, and python subscribers to implement on_event.

refactor: pull worker refcounting out of BatchManager Worker tracking (increment/decrement/active_workers) is an execution concern, not a buffer management concern. Move it to ExecutionContext where the caller coordinates flush readiness by combining batch_manager.can_flush() (buffer drained) with its own worker count. Also rename remove_input to drain — returns remaining buffered data instead of silently dropping it, preventing accidental data loss.

chore: regenerate uv.lock with uv 0.11.2, align pre-commit hook The lockfile generated by uv 0.9.2 had a missing transitive dependency (imagehash -> scipy 1.16.1) that caused parse failures in CI which runs uv 0.11.2. Regenerated with `uv lock --upgrade` on 0.11.2 and updated the uv-pre-commit hook from 0.9.22 to 0.11.2 to match. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

refactor: consolidate BatchManager as single buffer abstraction BatchManager now owns per-input buffers, worker tracking, and flush lifecycle — replacing the previous three-abstraction coordination between RowBasedBuffer, InputState, and BatchManager. This enables future data-aware batching strategies (e.g. explode expansion-aware batching) to override `next_batch` on BatchingStrategy and directly inspect/extract from the buffer. Key changes: - BatchManager absorbs InputState (removed) and manages per-input RowBasedBuffer internally - Add `next_batch` to BatchingStrategy trait with default row-count impl - ExecutionContext dispatch loop goes through BatchManager exclusively - Remove the broadcast loop that eagerly updated all buffer bounds - Requirements applied lazily inside BatchManager::next_batch - Add RowBasedBuffer::take_rows/partitions/total_rows for future data-aware strategies - Move BatchManager to its own module (batch_manager.rs), leaving dynamic_batching/ for strategy traits and implementations
