Robert Allan JamesandClaude Sonnet 5 77d8f0606a proof/: add StarForth_Dictionary_Manipulation_Words.thy ([/]/STATE/SMUDGE/HIDDEN/INTERPRET)
Covers the mode/flag half of dictionary_manipulation_words.c that's provable
against the existing vm_mode/dictionary/latest_id model. The raw-pointer
DictEntry navigation half (>BODY/>NAME/NAME>/>LINK/LINK>/CFA/LFA/NFA/PFA/
TRAVERSE/FIND/') is left unmodelled -- same class of gap as control_words.c's
deferred vm_ip/return-stack-as-raw-pointers issue, since the abstract
dict_entry record is word_id-indexed, not addressed, and has no counterpart
for struct-relative pointer arithmetic (name_len, link, body offset).

Genuine findings recorded in comments, not fixed:
- [, ], STATE, and INTERPRET all read/write a file-scope `static cell_t
  state_variable` -- NOT vm->state_var, the real per-VM STATE field used
  everywhere else in the interpreter. In the Tripod multi-VM fleet this
  static is shared across every VM instance, not per-VM.
- dictionary_m_word_hidden's dead #else branch (unreachable since
  WORD_HIDDEN is always defined) calls a function that doesn't exist
  (dictionary_word_smudge vs. the real static dictionary_m_word_smudge).

27 theory files verify with zero errors.
