fix(hive): support hyphenated config property names in SET statement (#487)

[liuxy0551]

Problem

HiveSQL.validate() reports a syntax error on config keys containing
hyphens, e.g. set tez.grouping.max-size = 1, while SparkSQL.validate()
accepts them. These keys are valid Hive SQL (Hive passes tez.* properties
through to the Tez session).

Changes

• src/lib/SQLParserBase.ts: add isNextTokenAdjacent() semantic predicate
  to check whether two tokens are adjacent (no whitespace).
• src/grammar/hive/HiveSqlParser.g4: rewrite SET statement to
  KW_SET configProperty EQUAL .*?; add configProperty / configPropertyPart
  to allow adjacent - between config key segments. Keeps the
  configPropertiesItem-based structure so SET <key> autocomplete still
  offers known keys.
• Regenerate src/lib/hive/HiveSqlParser.*.

Tests

• Positive cases added to test/parser/hive/syntax/fixtures/setConfigProperties.sql
  (tez.grouping.max-size etc.).
• Negative case: spaced set hive.a - b = 1; still reports an error.

Verification

• Hive full tests: 30 suites / 1189 tests passed.
• Full test suite: 220 suites / 6337 tests passed, no regressions.
• antlr4 --all --check, prettier-check, check-types, build all pass.

Closes #487
