fix: remove duplicate CI pipeline on push to main

[AndrewAltimit]

Summary

• Deleted .github/workflows/ci.yml -- this workflow triggered on push: branches: [main] with the exact same CI steps as main-ci.yml, causing every merge to main to run the full CI suite twice
• Updated CLAUDE.md to reflect the remaining two workflows instead of three
• main-ci.yml already handles all CI checks (fmt, clippy, test, build, deny, emulator) plus release binary creation and GitHub Release on tags/manual trigger -- ci.yml was entirely redundant

Test plan

• Verify main-ci.yml still runs on push to main (triggers section unchanged)
• Verify pr-validation.yml still runs on PR open/sync/reopen (untouched)
• Confirm only 1 pipeline fires on merge to main, not 2

Notes

• 2 claim(s) were automatically filtered as potential hallucinations (file:line content didn't match claims)

• The deletion of .github/workflows/ci.yml correctly removes redundant CI execution on the main branch.

• main-ci.yml contains all essential steps (formatting, linting, testing, building, and emulator tests) previously in ci.yml.

• main-ci.yml is correctly configured to trigger on push to main and includes additional logic for release binary creation and automated GitHub Releases on tags.

• CLAUDE.md documentation has been appropriately updated to reflect the simplified workflow structure.

• pr-validation.yml remains untouched and continues to provide comprehensive CI and AI-driven review coverage for pull requests.

Notes

• 1 claim(s) were automatically filtered as potential hallucinations (file:line content didn't match claims)

• Verified deleting .github/workflows/ci.yml leaves one push CI pipeline for main via .github/workflows/main-ci.yml.

• Verified .github/workflows/main-ci.yml still triggers on push to main, tags: v*, and workflow_dispatch; pr-validation.yml [UNVERIFIED - File does not exist and is not in PR] remains unchanged for PR events.

• Verified documentation update is consistent: CLAUDE.md:121 now accurately lists two workflows.
