v3.0.0 add word find_many tool

[3.0.0] - 2026-08-02

Added

• word_find_many tool — exact-match search for multiple terms in a single
  call. Accepts a list of 1-25 terms and returns one WordFindEntry
  (term + results) per input term, in the same order as the input, so
  a term matching zero, one, or several vocabulary entries is always
  represented positionally rather than as a flattened, ambiguous list.
  New models/word_find_entry.py (WordFindEntry model) and
  tools/words/word_find_many.py, registered in tools/words/__init__.py.
• asdste100://version MCP resource — installed version numbers of the MCP
  server itself (biz-dfch-asdste100mcp) and its three data-backing
  libraries: biz-dfch-asdste100vocab, biz-dfch-asdste100rules, and
  biz-dfch-asdste100nlp. Backed by importlib.metadata.version(); no
  network calls. New models/version_info.py (VersionInfo model) and
  resources/version.py, registered in resources/__init__.py.
• MCP resource support, in addition to tools:
  • asdste100://rules/toc — table-of-contents outline of the ruleset (mirrors
    the rules_toc tool with no section filter).
  • asdste100://rules/rule/{id_} — a single rule/recommendation/information
    item by exact id, e.g. asdste100://rules/rule/R1.1 (mirrors the
    rules_find tool).
  • New resources/ package (mirroring the existing tools/ package
    structure), with a rules/ sub-package for the rules resources;
    registered in server.py alongside the existing tools import.
  • tests/resources/rules/ — unit tests for both resource functions.

Changed

• Breaking: Renamed the Settings fields files, use_ste100,
  use_ste100_technical_words, and use_ste100_rules to vocab_files,
  use_asdste100_vocab, use_asdste100_technical_words, and
  use_asdste100_rules respectively (settings.py). Because
  Settings.model_config derives environment variable names from the
  field name under the ASDSTE100_MCP_ prefix, this also renames the
  corresponding environment variables: ASDSTE100_MCP_FILES →
  ASDSTE100_MCP_VOCAB_FILES, ASDSTE100_MCP_USE_STE100 →
  ASDSTE100_MCP_USE_ASDSTE100_VOCAB,
  ASDSTE100_MCP_USE_STE100_TECHNICAL_WORDS →
  ASDSTE100_MCP_USE_ASDSTE100_TECHNICAL_WORDS, and
  ASDSTE100_MCP_USE_STE100_RULES → ASDSTE100_MCP_USE_ASDSTE100_RULES.
  Update any .env file, shell environment, or deployment config that
  sets these variables under their previous names. server.py's lifespan
  function and tests/settings/test_factory.py were updated accordingly.
• Bumped the biz-dfch-asdste100vocab runtime dependency from >=0.8.0
  to >=0.8.1.
• Updated README.md wording in the Authentication section to mention
  resources alongside tools, and added a note about the MCP Inspector
  sometimes failing to connect over stdio (use sse instead).
