feat: scaffold standalone aavegotchi-cli foundation

[cinnabarhorse]

Summary

• completed the full v1 agent-first CLI foundation for Aavegotchi Base-era automation
• added signer backend coverage beyond env:
  • readonly
  • env:<ENV_VAR>
  • keychain:<accountId> with encrypted local key store (AGCLI_KEYCHAIN_PASSPHRASE)
  • remote:<url|address|authEnv> with HTTP signer protocol
  • ledger:<path|address|bridgeEnv> via bridge command protocol
• added signer management commands:
  • signer check
  • signer keychain import|list|remove
• extended bootstrap with signer backend config flags:
  • --signer-address
  • --signer-auth-env-var
  • --signer-bridge-env-var
• strengthened tx execution engine:
  • generic signer runtime abstraction for all signer backends
  • pre-submit balance sufficiency check
• completed parity routing behavior:
  • mapped write aliases now route regardless of stub-root gating
  • added missing domain roots (auction, staking, gotchi-points) to stub/read support
• prepared npm package metadata for public install:
  • package name set to aavegotchi-cli
  • publishConfig.access=public
  • clean build output before packaging (rm -rf dist)
• added CI + release workflows:
  • .github/workflows/ci.yml
  • .github/workflows/release.yml
• kept Base-era scope excluding raffle/ticket flows

Test Plan

• npm run typecheck
• npm test
• npm run build
• npm run parity:check
• npm run ag -- help
• NPM_CONFIG_CACHE=/tmp/aavegotchi-cli-npm-cache npm pack --dry-run
• AGCLI_HOME=/tmp/agcli-e2e-final npm run ag -- bootstrap --mode agent --profile prod --chain base --signer readonly --json
• AGCLI_HOME=/tmp/agcli-e2e-final AGCLI_KEYCHAIN_PASSPHRASE=passphrase-123 AGCLI_PRIVATE_KEY=0x1111111111111111111111111111111111111111111111111111111111111111 npm run ag -- signer keychain import --account-id bot --private-key-env AGCLI_PRIVATE_KEY --json
• AGCLI_HOME=/tmp/agcli-e2e-final npm run ag -- signer keychain list --json
• AGCLI_HOME=/tmp/agcli-e2e-final AGCLI_KEYCHAIN_PASSPHRASE=passphrase-123 npm run ag -- bootstrap --mode agent --profile bot --chain base --signer keychain:bot --json
• AGCLI_HOME=/tmp/agcli-e2e-final AGCLI_KEYCHAIN_PASSPHRASE=passphrase-123 npm run ag -- signer check --profile bot --json
• AGCLI_HOME=/tmp/agcli-e2e-final npm run ag -- auction bid --json (expected typed error: MISSING_ARGUMENT for --abi-file, confirms alias routing)
