chameleon 2.36.0

Added

• Comprehension surface: chameleon now does both conformance and
  comprehension. The committed conformance profile (symbol index, calls index,
  archetypes, canonicals) doubles as a queryable comprehension layer, so an
  assistant can understand and navigate existing code, not just shape new edits,
  off ONE profile, offline and with no repo-code execution. Three new MCP tools:

  • search_codebase(query) finds symbols by name or file from the committed
    symbol index, ranked exact name > prefix > substring > all-tokens > file-path
    with the more-called symbol breaking ties. The "where is X / find Y" query
    chameleon previously could not answer. Each result carries name, file, line,
    signature, and caller count; the result count is clamped to
    COMPREHEND_SEARCH_MAX_RESULTS.
  • describe_codebase() returns a structural overview from the profile: the
    primary language and framework, the archetypes (kinds of files, each with
    size, summary, and canonical witness), file/symbol totals, and the god
    symbols (the most-called production functions, test files excluded).
  • get_callees(file, function) answers "what does this function call"
    (forward edges) by inverting the reverse calls index, completing the
    navigation surface alongside get_callers and get_blast_radius, with the
    same three deterministic grades.

  All three are trust-gated, sanitized, fail open, and read only the committed
  artifacts. SymbolSignatures and CallsIndex gained items() accessors for
  the whole-index walks comprehension needs.
