* object path => entity path

* move utils from lib.rs to dedicated file

* color_rgba -> color_srgba_unmultiplied

* getting intimate with arrow's datamodel

* getting _even more_ intimate with arrow's datamodel

* split it

* building dem index keys

* disgustingly, incorrectly inserting components all the way down

* timelines need no list

* similarly clarifying the nested listing situation, on the components side this time

* make sure it looks like it should!

* actual integration tests

* bootstrapping text-based debugging

* bootstrapping indices

* introducing TypedTimeInt everywhere

* full index sorting

* auto-inserting empty component lists in starting buckets

* better datagen tools

* bidirectional merges for indices + properly showing NULLs in dataframes

* finally can show off some more advanced ingestion patterns!

* dealing with corrupt validity bitmaps, and the sheer size of my stupidity

* read path taking its first steps: latest_at for indices!

* look! it's a read path!

* it works!

* show the resulting dataframe duh

* clean up pass #1: task log

* clean up pass #2: moving everybody where they belong

* clean up pass #3: definitions

* a minimal solution for missing components

* some more cleanup

* porting relevant TODOs into issues

* appeasing the CI deities

* merge catastrophe

* they see me cleanin', they hatin'

* * Reorg of re_arrow_store
* Removed up old ArrowDB code
* Connected app data ingest into new DataStore

* fix broken doc links

* store files prefixed with store_

* integration tests in integration folder + exposing datagen tools to everyone

* make integration tests scale to more complex scenarios

* adding currently failing scenario: query before any data present

* added failing test and scenarios for all emptines-related edge cases

* better testing tools

* fixing broken edge cases on read path

* demonstrating faulty read behavior in roundtrip test

* fixing dem faulty swaps

* when the doc itself demonstrates bugs :x

* adding baseline bench somewhat mimicking the legacy ones, though it doesn't really make sense anymore

* exploding query results so you can actually do stuff with them

* properly testing all halfway frames (and, unsurprisingly, failing!)

* properly dealing with multi-row primary indices

* less verbose scenarios for end-to-lend latest_at tests

* addressing misc PR comments

* TimeReal, TimeRange & TimeRangeF are now a properly of re_log_types™

* retiring TypedTimeRange before Emil tries to hurt it

* mark unreachable as such

* replaced binary_search with a partition_point

* using entity path hashes directly in indexing datastructures

* re_viewer don't need those no more

## Issue #3: Extract magic string to constant
- Created _EMPTY_FILTER_PATH constant for "/__rerun_internal__/non_existent"
- Replaced 4 occurrences of the magic string with the constant
- Improves maintainability and clarity

## Issue #4: Add comprehensive empty filter tests
Added 4 new tests for edge cases:
- test_filter_archetypes_multiple_nonexistent: Verify multiple nonexistent archetypes return empty view
- test_filter_archetypes_empty_view_can_be_read: Verify empty views can be read without crashes
- test_filter_component_types_multiple_nonexistent: Verify multiple nonexistent component types return empty view
- test_filter_component_types_empty_view_can_be_read: Verify empty component type views can be read

These tests ensure robust handling of empty results and verify that the
constant behavior (returning empty view) works correctly.
