…nologies#69)

Usability improvements for the case of examining a single object, easier pipe support etc.

Also extensive cleanup of the implementation, and more extensive test coverage, to put us in better position to add other improvements in upcoming PRs (hex, array hashing, JSON support etc)

TypeIdRegistry maps Unity ClassIDs (PersistentTypeID) to type names. It is
needed as a fallback when a serialized object's TypeTree is unavailable, and
when only an ID is known with no file to read at all (e.g. resolving the type
of a PackedAsset referenced from a BuildReport). In those cases the name cannot
be recovered from the data, so a static map in the tool is required.

The map was previously built by hand from the public ClassIDReference page and
pruned manually, with no repeatable way to refresh it as new types are added.
TypeIdRegistryGenerator (hosted in the UnityFileSystemTestData project) now
produces the entries from the live engine type list (UnityEditor.UnityType):
runtime types are kept, editor-only types are dropped via the isEditorOnly
flag, a small allowlist of BuildReporting types is force-included (needed for
BuildReport inspection), and test/fake types from development builds are
filtered out. Run it via Tools/Generate TypeIdRegistry or -executeMethod to
regenerate the block for a new Unity version.

…sources; add --skip-crc (Unity-Technologies#73)

Fixes for CRC calculation
Refactor and improve maintenance of PPtrAndCrcProcessor

…s#75)

Add Documentation/contentlayout.md describing the ContentLayout.json file
produced by content directory builds, and publish the C# schema as a copy of
the Unity source type. 

Move the JSON model classes (BuildLayout, ContentLayout)
into a new dependency-free UnityDataModels project so they are easier to find
and can be reused by tools that don't depend on the analyzer or SQLite.

…and docs improvements (Unity-Technologies#76)

* Add some description for UnityDataTool --help
* AnalyzeTool - pass parameters through structure
* [Unity-Technologies#49] Allow analyze to accept multiple file or directory paths
* Clarify UnityFileSystemApi section in README

…and dump (Unity-Technologies#78)

Analyzing AssetBundles whose SerializedFiles have no TypeTrees handed the
files to the native loader, which emitted misleading "Invalid serialized
file version" errors and could crash the process with an access violation
(0xC0000005)

Fix is to detect missing TypeTrees before the native open and skip such files cleanly,

Fix applies to both dump and analyze commands.
Fix applies to Player data and other build types in addition to AssetBundles.

Bump version now that 1.3.5 binaries have been published.

Replace update to builds extracted from 6000.6.0a7

* Windows was extracted by installing and copying file from C:\Program Files\Unity 6000.6.0a7\Editor\Data\Tools
* Linux was extracted from Unity-6000.6.0a7.tar.xz from Unity-6000.6.0a7.tar.xz\Unity-6000.6.0a7.tar\Editor\Data\Tools\ (Using 7z)
* OSX was extracted from ARM64 build Unity-6000.6.0a7.pkg from Unity.pkg.tmp\Payload\Payload~\.\Unity\Unity.app\Contents\Frameworks\ (Using 7z)

…ase/null-ref bugs (Unity-Technologies#79)

* Introduce second UnityProject

Rename UnityFileSystemTestData and introduce a LeadingEdge project for testing Content Directory builds and other newer features that require Unity >=6.6.
Add AGENTS.md explaining the relationship between these projects and the referenced files checked in to TestCommon

* Dump command tested with core numeric field types and other serialization primitives

* [Unity-Technologies#72] Fix find-refs database open and null-ref crashes, add test coverage

find-refs had no automated tests and two bugs that broke it against any
current analyze database:

- Issue Unity-Technologies#72: the database was opened with a hand-written connection string
  using the legacy System.Data.SQLite "Version=3" keyword, which
  Microsoft.Data.Sqlite rejects. Build the connection string with
  SqliteConnectionStringBuilder instead (matching SQLiteWriter). Fixed the
  same broken string in ExpectedDataGenerator.

- A ScriptableObject is a MonoBehaviour whose m_GameObject PPtr is 0, so its
  game_object column is a non-null id matching no row; the game_object/script
  subqueries then return NULL and GetString threw. Null-check those reads.

Also add a --stdout option to find-refs (mutually exclusive with -o), mirroring
dump, and update command-find-refs.md.

Add FindRefsTests covering both bugs, name/type lookup and disambiguation,
object-id lookup, --find-all, missing objects, empty refs table, the
--stdout/-o validator, and direct refs-table queries. Tests run against the
LeadingEdge AssetBundle reference build.

…strings (Unity-Technologies#80)

* Update version to 2.0 - Major version bump because the analyze schema will get some changes.

* [Unity-Technologies#44] Normalize refs table to deduplicate property strings

The refs table repeated the property_path/property_type strings on every
row, making it by far the largest part of the analyze database. Store the
strings once in new property_names/property_types lookup tables and keep only
integer ids in refs. A refs_view rejoins them to expose the original strings.

- Fix view_material_texture_refs, which used double-quoted string literals
  that SQLite parsed as identifiers (pre-existing, failed on old databases too).

* Adjust expected link to build reporting documentation

…spects of the Analyze schema

add comments explaining some of the less intuitive aspects of the assets and asset_dependencies table, and when it is actually populated.
Document also special case handling of scene roots (including mention of a discovered bug, issue 81)
