rename canvas → program - #562

Conversation
Rename the per-session orchestration "canvas" to "program" across the
whole surface: MCP tools (construct_program_*), wire-protocol methods
(program.*), CLI verbs (construct program ...), protocol types (Program*),
client methods, TUI labels/tooltips, the autonomous run contract, and
specs 0041–0050 (files + content).
On-disk artifacts move from canvas.{md,json}, canvas-revisions.jsonl,
canvas-run-context.json and data/canvas/templates to their program.*
counterparts, with a lazy, idempotent migration on first read so existing
sessions keep their content (no manual steps, no data loss).
Vendored xterm assets and the mini-matrix <canvas> element (index.html,
web_smoke.rs) are genuine HTML canvases unrelated to this feature and are
intentionally left untouched.

Renames the per-session orchestration surface from canvas to program across the entire stack. Pure rename — no behavior change beyond the names.
