Loki Mode

Added

• Claude session-id stamping (Phase 1, correlation-only): every run writes a
  deterministic per-run UUID (UUIDv5 of the trust-run-id) to
  .loki/state/claude-session.json and surfaces it as claude_session_id on
  the dashboard /api/status, so a run can be correlated with its Claude
  session. Opt-in LOKI_SESSION_STAMP=1 additionally passes a distinct
  per-iteration --session-id to the main-loop Claude call (never to subcalls;
  never a pinned id across the run, so context is not accumulated). Default OFF
  keeps the Claude argv byte-identical to v7.33.0. Bash and Bun routes derive
  the same UUID byte-for-byte. Gated on CLI support.
• LOKI_NO_SESSION_PERSIST=1 (opt-in, default OFF): passes
  --no-session-persistence so a run leaves no Claude session state on disk
  (useful for ephemeral/CI runs). Gated on CLI support.
• Both new env knobs documented in wiki/Environment-Variables.md;
  claude_session_id documented in wiki/API-Reference.md.

Fixed

• CLI honesty: loki config help no longer advertises a nonexistent
  config provider subcommand; cold loki status tips now point at the
  canonical loki analyze context show / loki analyze code overview
  (instead of deprecated aliases that emitted a deprecation note); README.md
  and docs/INSTALLATION.md use the canonical command names
  (loki modernize heal, loki analyze onboard, loki preview,
  loki api start) with "was:" annotations.
