Add project-local CLI routing for skills-based setup

[hmishra2250]

Summary

• add the project-local CLI-capability router card used by the powered P2 study
• install it by default when firecrawl init completes an eligible project state: authenticated CLI, installed skills, explicit Claude/Codex agent, and explicit project path
• provide --no-router-card as a per-run opt-out and --remove-router-card as a bounded removal command
• preserve existing user context through a delimited, idempotent managed block

Exact journey

Default-on eligible setup:

firecrawl init --yes --agent claude --project /path/to/project
# or
firecrawl init --yes --agent codex --project /path/to/project

This writes only the project-local native context file (CLAUDE.md for Claude, AGENTS.md for Codex). It does not write a global instruction file.

Opt out for one run:

firecrawl init --yes --agent claude --project /path/to/project --no-router-card

Remove only the managed block without rerunning onboarding:

firecrawl init --agent claude --project /path/to/project --remove-router-card

Package installation alone, login/logout, unsupported agents, missing authentication, skipped skills, and commands without an explicit project do not write a card.

Decision-grade evidence

P2 ran 384 immutable Convex-backed traces across Claude Sonnet 5 and Codex Terra at 30-way E2B concurrency.

• card with native web available: 50% → 100%, +50pp pooled, Holm-adjusted p ≈ 0.000003
• Claude: 0% → 100%, +100pp; Codex: 100% → 100%, ceiling/null
• safety: 0/96 treatment-only regressions; simultaneous upper bound 4.18%, passes the preregistered <5% gate
• native-web suppression was independently rejected: 21/96 regressions and no incremental benefit once the card was present

Recommendation: ship this project-local card for the CLI + skills state and leave native web tools available. The result transfers by machine-state equivalence, not by command-name similarity.

Aggregate decision artifact: Convex kg2e1vb0xg4k95v70wb2ahzn018arvnv. Raw traces and receipts are not stored in Git.

Scope

This draft does not write global CLAUDE.md/AGENTS.md, mutate project files during package install or login/logout, or suppress native web tools. Additional onboarding aliases should adopt the card only after a small state-parity canary.
