fix(rig-worktree,install): resolve script and doc paths per install target

[pgebheim]

Follow-up to #69 / #70 — the adjacent bug flagged in #70's description.

Problem

Two paths were hardcoded to .claude/ with no indirection, so on an agents-md-only repo (Codex, Cursor, Gemini CLI — exactly the population #69 and #70 exist to serve) they pointed at files that aren't there.

1. rig-worktree named .claude/scripts/{setup,remove}-worktree.sh in four places. The agents-md target installs those scripts to .rig/scripts/, and such a repo has no .claude/ at all. The skill told the agent to run a path that doesn't exist — immediately after insisting it must not reimplement the script inline.

2. install.sh copied rig.config.example.json verbatim, so every install got review.patternsFile: .claude/REVIEWER.md and tracker.labelMapFile: .claude/label-mapping.md. Without the claude-code target those docs land in .rig/, leaving both keys dangling on a fresh install.

Change

• <SCRIPTS> resolver in rig-worktree: first-hit-wins over .claude/scripts/ then .rig/scripts/, in the spirit of the <TRACKER> resolver that rig-epic/rig-task/rig-issue/rig-doctor/rig-plan already use. Stops with a clear message if neither has the script. The scripts themselves already resolved their own siblings — only the callers needed fixing.
• install.sh rewrites the two doc paths when claude-code isn't among the targets. Uses an inline membership test rather than a helper, to stay independent of fix(install): one payload on dual-target installs, .claude/ symlinked at it #70.
• docs/config.md notes the per-target default for both keys.
• Fixed a stale rig/scripts/ → .rig/scripts/ comment in setup-worktree.sh (left over from refactor(install): put the agents-md payload under .rig/ (one rig home) #63).

Deliberately unchanged

.claude/worktrees/ as the default worktree location. The Claude Code harness only adopts worktrees there (41283b3), so it stays; it's now documented as carrying no special meaning on other agents, with --path to override.

Verification

Ran all three install shapes, executed the resolver snippet exactly as the skill now prescribes against each, and checked every configured doc path resolves to a real file:

shape	patternsFile	exists	labelMapFile exists	resolver →
claude-only	.claude/REVIEWER.md	yes	yes	.claude/scripts
agents-only	.rig/REVIEWER.md	yes	yes	.rig/scripts
dual	.claude/REVIEWER.md	yes	yes	.claude/scripts

bun test scripts/ — 39 pass.

Caught during verification: an earlier draft used has_target, a helper that only exists on #70's branch. Undefined here, the check silently inverted and clobbered the claude-only config. Hence the inline test — and it's why the table above checks exists per shape rather than just eyeballing the written value.
