Adapt to wire-sysio table_id namespace isolation; long table name support

[heifner]

Summary

Wire-sysio PR Wire-Network/wire-sysio#288 widened table_def.name from sysio::name (uint64) to free-form std::string and added table_id (uint16, DJB2 hash of the table name % 65536) and secondary_indexes for KV-table per-table namespace isolation. The binary wire format break means abieos must be updated in lockstep with the chain side or every field after tables in abi_def parses misaligned, and any contract whose table name is longer than 12 chars is unreachable through the C API.

This PR takes the chance to make the long-table-name story end-to-end by switching the internal table_types map and the C API entry point to free-form strings.

⚠️ Breaking C API change

abieos_get_type_for_table now takes the table name as a const char* instead of a uint64-encoded sysio name:

// Before
const char* abieos_get_type_for_table(abieos_context*, uint64_t contract, uint64_t table);
// After
const char* abieos_get_type_for_table(abieos_context*, uint64_t contract, const char* table);

The only known consumer of this entry point in the Wire ecosystem is node-abieos (the native binding used by Wire-Network/hyperion-history-api), which was already converting JS strings to uint64 via abieos_string_to_name() before calling this function — that round trip is now redundant and node-abieos can pass the string straight through. node-abieos will be updated in a follow-on PR.

Changes

include/sysio/abi.hpp

• New index_def struct: {name: string, key_type: string, table_id: uint16} mirroring sysio::chain::index_def
• table_def: name: name → string, +table_id: uint16, +secondary_indexes: index_def[]
• abi_def: +protobuf_types as a might_not_exist<std::string> extension to mirror wire-sysio's reflection layout (variants, action_results, enums, protobuf_types). Keeps binary forward-compat for ABIs that include the field even though abieos itself doesn't consume it.
• abi.table_types: std::map<sysio::name, string> → std::map<std::string, std::string, std::less<>>. The std::less<> transparent comparator lets callers do find(string_view) without constructing a temporary std::string per lookup.
• abi.abi_types likewise gets std::less<>.
• New aliases: table_type_map, abi_type_map (used in abi.cpp signatures).
• to_json(abi_def) writes protobuf_types unconditionally for consistency with the surrounding extension fields (variants, action_results, enums) which always emit even when empty.

src/abieos.hpp

• jobject typedef gets std::less<> for the same transparent-lookup reason — the JSON object map is the hottest map in abieos.

src/abi.cpp

• convert(abi_def, abi) populates table_types directly with the new string-typed table_def.name; no name conversion needed.
• Function signatures updated to use abi_type_map alias.

src/abieos.h, src/abieos.cpp

• abieos_get_type_for_table signature change as described above.
• Internal lookup uses std::string_view via the std::less<> transparent comparator to avoid an allocation per call.

src/test.cpp

• tokenHexAbi regenerated for the new binary format. The token ABI shape (sysio::abi/1.0) is unchanged, but the on-wire encoding of tables[].name is now a length-prefixed string instead of a uint64. The new hex was produced from the canonical token ABI JSON via abieos_abi_json_to_bin().

external/wirejs-native

• Submodule pointer bumped to feature/wire-sysio-table-id (Update abi_def schema for wire-sysio table_id namespace isolation wirejs-native#4) which mirrors the schema changes on the TypeScript side.

Tests

All four C++ tests pass against the updated layout:

• test_abieos
• test_abieos_template
• test_abieos_key
• test_abieos_reflect
