chameleon 2.58.0

Added

• A standalone ruff.toml / .ruff.toml is now read for formatting conventions.
  _read_python_format only mined [tool.ruff] from pyproject.toml, so the
  large population of repos that keep ruff config in a standalone file (ruff's
  own .ruff.toml > ruff.toml > pyproject.toml discovery order) had their
  line-length, quote-style, indent-style, and indent-width silently
  dropped — rules_extracted came back 0 and the derived formatting convention
  was blank. The reader now resolves the ruff config the way ruff does: a
  standalone file takes precedence over [tool.ruff] and the two are never
  merged (matching ruff's real behavior), with black still read independently
  from [tool.black] and the flake8/pycodestyle line-length fallback intact.
  The pyproject.toml-only path is unchanged. Verified end-to-end: a repo with
  a standalone ruff.toml (line-length = 120, [format] quote-style = single)
  now derives python_format {line_length: 120, quote_style: single, source: ruff.toml} into rules.json. Found by the from-scratch QA sweep against a
  real Django fixture.

Fixed

• A resolved profile no longer advises bootstrapping a frontend it already
  bootstrapped. A Python or Rails repo with a JS/TS frontend emits a
  language_hint telling the user to run bootstrap_repo(.../frontend) for the
  JS half. When that frontend is a declared workspace, the same run already
  bootstrapped it, so that advice is stale. Bootstrap now drops the hint from
  the envelope, profile.json, AND the rendered profile.summary.md when a
  successfully bootstrapped workspace IS that frontend subdir or lives inside it.
  It is careful to only fire on the frontend-subdir hints: the other hint shape
  (TypeScript won at the root but a sibling Ruby/Python tree lives somewhere in
  the repo) names the whole repo root, and a package workspace never covers that
  separate-language tree, so those hints always survive; an unrelated or
  merely-ancestor workspace never suppresses a still-valid frontend hint either.
  The reconciliation rides the shared derivation path, so a stale hint on an
  existing profile is cleaned up on the next /chameleon-refresh.

• initialize now reports the chameleon build as serverInfo.version. The
  stdio server passed no version to FastMCP, so serverInfo.version defaulted
  to the installed mcp SDK's own package version (1.27.1) — a client could
  not correlate the running server to the installed plugin. It now reports the
  plugin build (2.58.0), set on the wrapped low-level server and guarded so a
  future SDK internals change can never crash startup over a cosmetic string.

• describe_codebase documents its unsupported-schema shape. The docstring
  promised found: False on an unresolvable/untrusted repo but did not cover a
  resolved profile whose schema_version is newer than the engine supports,
  which returns found: True with degraded: True and the profile-derived
  fields nulled — an honest "a profile exists but is unusable under this engine"
  signal (distinct from "no profile at all"), the same state detect_repo
  reports as profile_unsupported_schema_version. Behavior was already correct;
  the contract is now accurate. Consumers must check degraded before reading
  the derived fields.
