The /save script documentation lived as a hand-maintained string in
Agent.zig whose primitives table drifted whenever a tool changed. Move
it to src/script/skill.zig and render the reference (signatures, option
lists, enums, defaults, per-parameter descriptions) from Schema.all()
at first use, keeping the curated per-tool notes behind an exhaustive
switch on Tool so a new or renamed tool is a compile error until its
doc entry exists.
The rendered skill is shared by three consumers:
- the /save and revision system prompts (built lazily in Agent.zig)
- a new mcp://skill/pandascript resource
- `zig build skills`, which writes zig-out/skills/<name>/SKILL.md with
Claude Code frontmatter via a registry-based generator exe, so
future Lightpanda skills are one registry entry each
Schema.FieldEntry now retains per-parameter schema descriptions, which
previously existed only in the raw JSON.
