v0.2.0

Added

• NsisInstaller::format_entry(&Entry) -> String for rendering an opcode
  mnemonic plus decoded parameters as a script-like line.
• NsisInstaller::format_entry_params(&Entry) -> String for consumers that
  need reusable opcode-aware parameter formatting without reimplementing the
  string/variable/jump decoding rules.
• NsisInstaller::script_analysis() for script-level control-flow analysis,
  including roots, functions, basic blocks, edges, entry-to-block mapping, and
  diagnostics for invalid targets.
• Symbol-aware formatting via format_entry_with_analysis() and
  format_entry_params_with_analysis(), which annotate jump and call targets
  with names from ScriptAnalysis.

Changed

• The dump example now uses the crate-provided instruction formatting API.
• The dump example uses script analysis symbols when rendering control-flow
  targets.
• Opcode metadata now matches NSIS operand layouts more closely for stack,
  UI, execution, registry, and file I/O instructions.

Fixed

• EW_PUSHPOP formatting now treats param0 as a variable for Pop and as a
  string for Push, preventing variable IDs from being decoded as offsets into
  unrelated strings such as ProgramFilesDir.
• Corrected high-level accessor layouts for ShellExecOp and RegDelete.
• Corrected several opcode parameter layouts and types, including
  EW_GETFULLPATHNAME, EW_INTOP, EW_INTFMT, EW_FINDWINDOW,
  EW_SENDMESSAGE, EW_GETDLGITEM, EW_SHELLEXEC, EW_DELREG, EW_FOPEN,
  EW_FSEEK, and EW_FINDFIRST.
