chameleon 2.29.0

Persistent trust, prompt-injection hardening across every model-facing surface,
and the remaining language and framework parity gaps. Trust is now one-time by
default, which removed the staleness gate that had doubled as the injection
defense, so screening moved to each point that renders committed-profile data to
the model.

Changed

• Trust is one-time by default. Once a repo is trusted it stays trusted
  across refresh, re-bootstrap, and teach, and never goes stale, so you never
  re-grant. Set CHAMELEON_TRUST_REVALIDATE=1 to restore the old behavior where
  any change to the trust-hashed profile surface re-prompts for a fresh
  /chameleon-trust.

Security

• Prompt-injection screening at the read and render site. Because a profile
  poisoned after you grant trust is no longer re-reviewed, every channel that
  renders committed-profile data to the model now screens it: the SessionStart
  block, the per-edit echo, the PreToolUse deny and PostToolUse block reasons,
  and the model-facing read tools (get_idiom_coverage, get_rules,
  get_status, get_archetype, get_pattern_context). Injection-prose keys and
  values are dropped and tag-boundary tokens neutralized; code- and path-bearing
  tools stay on tag-only screening so real symbols, signatures, and globs are not
  false-dropped. apply_archetype_renames now sources conventions from the raw
  on-disk artifact, so a legitimate value that trips the heuristic is never
  erased on rename.

Added

• Language and framework parity. Closed the remaining gaps across
  TypeScript, Ruby, and Python and the Django, DRF, Flask, and FastAPI framework
  layers, including a framework classifier and a DRF authorization-guard lint.

Fixed

• Ruby command-injection lint anchors on double-quoted strings (single-quoted
  strings do not interpolate), fixing a false positive on system '...#{x}...'
  and the missed system "...'#{x}'..." shell-wrapper idiom.
• Ruby insecure-deserialization lint now covers YAML.load_file,
  YAML.load_stream, and YAML.unsafe_load; safe_load stays excluded.
• Python authorization-guard lint matches PEP 695 generic class bases
  (class V[T](Mixin):), so a properly-guarded generic view is no longer
  flagged.
• ts_dump drops string-literal ambient module names (declare module "x")
  from the enclosing class path instead of pushing the literal name.
• The Python framework classifier reads dependency sections structurally
  instead of matching whole-file prose, so a description that mentions a
  framework no longer mis-classifies.
