gloas: add read only wrapper for payload envelope

This PR moves kzg commitments to bid. The rationale behind is captured
in this [issue](https://github.com/ethereum/consensus-specs/issues/4870)
* Moves blob KZG commitments to the earlier point where builder intent
is known
* Removes duplicated commitments from data column sidecars which saves
descent b/w per slot
* Enables nodes to start fetching blobs via getBlobs as soon as the bid
is received
* Slightly increases bid size and may add minor bidding channel latency
but the tradeoff favors lower network load and simpler DA handling

+# SSZ Query Package
+
+The `encoding/ssz/query` package provides a system for analyzing and querying SSZ ([Simple Serialize](https://github.com/ethereum/consensus-specs/blob/master/ssz/simple-serialize.md)) data structures, as well as generating Merkle proofs from them. It enables runtime analysis of SSZ-serialized Go objects with reflection, path-based queries through nested structures, generalized index calculation, and Merkle proof generation.
+
+This package is designed to be generic. It operates on arbitrary SSZ-serialized Go values at runtime, so the same query/proof machinery applies equally to any SSZ type, including the BeaconState/BeaconBlock.
+
+## Usage Example
+
+```go
+// 1. Analyze an SSZ object
+block := &ethpb.BeaconBlock{...}
+info, err := query.AnalyzeObject(block)
+
+// 2. Parse a path
+path, err := query.ParsePath(".body.attestations[0].data.slot")
+
+// 3. Get the generalized index
+gindex, err := query.GetGeneralizedIndexFromPath(info, path)
+
+// 4. Generate a Merkle proof
+proof, err := info.Prove(gindex)
+
+// 5. Get offset and length to slice the SSZ-encoded bytes
+sszBytes, _ := block.MarshalSSZ()
+_, offset, length, err := query.CalculateOffsetAndLength(info, path)
+// slotBytes contains the SSZ-encoded value at the queried path
+slotBytes := sszBytes[offset : offset+length]
+```
+
+## Exported API
+
+The main exported API consists of:
+
+```go
+// AnalyzeObject analyzes an SSZ object and returns its structural information
+func AnalyzeObject(obj SSZObject) (*SszInfo, error)
+
+// ParsePath parses a path string like ".field1.field2[0].field3"
+func ParsePath(rawPath string) (Path, error)
+
+// CalculateOffsetAndLength computes byte offset and length for a path within an SSZ object
+func CalculateOffsetAndLength(sszInfo *SszInfo, path Path) (*SszInfo, uint64, uint64, error)
+
+// GetGeneralizedIndexFromPath calculates the generalized index for a given path
+func GetGeneralizedIndexFromPath(info *SszInfo, path Path) (uint64, error)
+
+// Prove generates a Merkle proof for a target generalized index
+func (s *SszInfo) Prove(gindex uint64) (*fastssz.Proof, error)
+```
+
+## Type System
+
+### SSZ Types
+
+The package now supports [all standard SSZ types](https://github.com/ethereum/consensus-specs/blob/master/ssz/simple-serialize.md#typing) except `ProgressiveList`, `ProgressiveContainer`, `ProgressiveBitlist`, `Union`, and `CompatibleUnion`.
+
+### Core Data Structures
+
+#### `SszInfo`
+
+The `SszInfo` structure contains complete structural metadata for an SSZ type:
+
+```go
+type SszInfo struct {
+   sszType       SszType           // SSZ Type classification
+   typ           reflect.Type      // Go reflect.Type
+   source        SSZObject         // Original SSZObject reference. Mostly used for reusing SSZ methods like `HashTreeRoot`.
+   isVariable    bool              // True if contains variable-size fields
+
+   // Composite types have corresponding metadata. Other fields would be nil except for the current type.
+   containerInfo *containerInfo
+   listInfo      *listInfo
+   vectorInfo    *vectorInfo
+   bitlistInfo   *bitlistInfo
+   bitvectorInfo *bitvectorInfo
+}
+```
+
+#### `Path`
+
+The `Path` structure represents navigation paths through SSZ structures. It supports accessing a field by field name, accessing an element by index (list/vector type), and finding the length of homogenous collection types. The `ParsePath` function parses a raw string into a `Path` instance, which is commonly used in other APIs like `CalculateOffsetAndLength` and `GetGeneralizedIndexFromPath`.
+
+```go
+type Path struct {
+   Length   bool           // Flag for length queries (e.g., len(.field))
+   Elements []PathElement  // Sequence of field accesses and indices
+}
+
+type PathElement struct {
+   Name  string  // Field name
+   Index *uint64 // list/vector index (nil if not an index access)
+}
+```
+
+## Implementation Details
+
+### Type Analysis (`analyzer.go`)
+
+The `AnalyzeObject` function performs recursive type introspection using Go reflection:
+
+1. **Type Inspection** - Examines Go `reflect.Value` to determine SSZ type
+   - Basic types (`uint8`, `uint16`, `uint32`, `uint64`, `bool`): `SSZType` constants
+   - Slices: Determined from struct tags (`ssz-size` for vectors, `ssz-max` for lists). There is a related [write-up](https://hackmd.io/@junsong/H101DKnwxl) regarding struct tags.
+   - Structs: Analyzed as Containers with field ordering from JSON tags
+   - Pointers: Dereferenced automatically
+
+2. **Variable-Length Population** - Determines actual sizes at runtime
+   - For lists: Iterates elements, caches sizes for variable-element lists
+   - For containers: Recursively populates variable fields, adjusts offsets
+   - For bitlists: Decodes bit length from bitvector
+
+3. **Offset Calculation** - Computes byte positions within serialized data
+   - Fixed-size fields: Offset = sum of preceding field sizes
+   - Variable-size fields: Offset stored as 4-byte pointer entries
+
+### Path Parsing (`path.go`)
+
+The `ParsePath` function parses path strings with the following rules:
+
+- **Dot notation**: `.field1.field2` for field access
+- **Array indexing**: `[0]`, `[42]` for element access
+- **Length queries**: `len(.field)` for list/vector lengths
+- **Character set**: Only `[A-Za-z0-9._\[\]\(\)]` allowed
+
+Example:
+```go
+path, _ := ParsePath(".nested.array_field[5].inner_field")
+// Returns: Path{
+//   Elements: [
+//     PathElement{Name: "nested"},
+//     PathElement{Name: "array_field", Index: <Pointer to uint64(5)>},
+//     PathElement{Name: "inner_field"}
+//   ]
+// }
+```
+
+### Generalized Index Calculation (`generalized_index.go`)
+
+The generalized index is a tree position identifier. This package follows the [Ethereum consensus-specs](https://github.com/ethereum/consensus-specs/blob/master/ssz/merkle-proofs.md#generalized-merkle-tree-index) to calculate the generalized index.
+
+### Merkle Proof Generation (`merkle_proof.go`, `proof_collector.go`)
+
+The `Prove` method generates Merkle proofs using a single-sweep merkleization algorithm:
+
+#### Algorithm Overview
+
+**Key Terms:**
+
+- **Target gindex** (generalized index): The position of the SSZ element you want to prove, expressed as a generalized Merkle tree index. Stored in `Proof.Index`.
+  - Note: The generalized index for root is 1.
+- **Registered gindices**: The set of tree positions whose node hashes must be captured during merkleization in order to later assemble the proof.
+- **Sibling node**: The node that shares the same parent as another node.
+- **Leaf value**: The 32-byte hash of the target node (the node being proven). Stored in `Proof.Leaf`.
+
+**Phases:**
+
+1. **Registration Phase** (`addTarget`)
+> Goal: determine exactly which sibling hashes are needed for the proof.
+
+   - Record the target gindex as the proof target.
+   - Starting from the target node, walk the Merkle tree from the leaf (target gindex) to the root (gindex = 1).
+   - At each step:
+     - Compute and register the sibling gindex (`i XOR 1`) as “must collect”.
+     - Move to the parent (`i = i/2`).
+   - This produces the full set of registered gindices (the sibling nodes on the target-to-root path).
+
+2. **Merkleization Phase** (`merkleize`)
+> Goal: recursively merkleize the tree and capture the needed hashes.
+
+   - Recursively traverse the SSZ structure and compute Merkle tree node hashes from leaves to root.
+   - Whenever the traversal computes a node whose gindex is in registered gindices, store that node’s hash for later proof construction.
+
+3. **Proof Assembly Phase** (`toProof`)
+> Goal: create the final `fastssz.Proof` object in the correct format and order.
+
+```go
+// Proof represents a merkle proof against a general index.
+type Proof struct {
+	Index  int
+	Leaf   []byte
+	Hashes [][]byte
+}
+```
+
+   - Set `Proof.Index` to the target gindex.
+   - Set `Proof.Leaf` to the 32-byte hash of the target node.
+   - Build `Proof.Hashes` by walking from the target node up to (but not including) the root:
+     - At node `i`, append the stored hash for the sibling (`i XOR 1`).
+     - Move to the parent (`i = i/2`).
+   - The resulting `Proof.Hashes` is ordered from the target level upward, containing one sibling hash per tree level on the path to the root.
