opencode native 0.3.0

Added

• Statistics of a session: the header's token count (and Ctrl+I, the menu) opens them: totals in tiles (tokens in,
  out, reasoning, cost, cache hits), the context the last step filled against the model's window, tokens in detail, time
  (created, last change, the model at work, output pace), tool calls by tool with failures, models, sub-agents, and the
  project's totals from the server (sessions, sub-agents, prompts, steps, tokens, cost, active days, streak, tools with
  their median duration, models).
• Markdown tables as grids: columns as wide as their cells, the header row bold on a tint, alignments from the
  separator row, alternate rows shaded (they were shown as raw text in a code block).
• Screenshots in the README; --search=<text> fills the sidebar's search at start, --stats opens the statistics.

Fixed

• Dragging the conversation's scrollbar moved nothing while it followed its bottom (the drag, applied before the build,
  was undone by the following).
• The halo of a lit button reached the carved edge above it and darkened under it (tighter now).

Changed

• CI: actions/checkout v7, actions/cache v6, actions/upload-artifact v7 (Node 24); the MSVC environment is set by a
  step of the setup action (vcvars64 through vswhere) instead of ilammy/msvc-dev-cmd, whose releases still run on Node 20.

One executable for Windows 10 and 11 (x64): run it, or install it for your user from its Setup (title bar menu > Setup...). It finds the opencode desktop app's server by itself.
