[codex] Document fork provenance baseline

[Pectics]

Summary

Closes #1.

• add NOTICE.md with Mihoto fork attribution, upstream MIT license retention, and the mihoro-v0.14.0-base baseline
• add docs/fork-baseline.md documenting upstream/fork provenance, rename matrix, CI expectations, and safety baseline rules
• update README and Cargo metadata to point governance/project metadata at Pectics/mihoto while keeping inherited mihoro runtime names unchanged

Upstream references reviewed

• spencerwooo/mihoro upstream repository
• upstream v0.14.0 commit e31827ed257e7ce97217cd0a2dbcd1ef96dbac7f
• remote tag mihoro-v0.14.0-base, created as an immutable annotated baseline tag in Pectics/mihoto

Impact

• Migration impact: none; this is documentation and package metadata only, with no runtime rename or config migration.
• Security impact: documents the safety baseline and secret-redaction expectations; no secrets or subscription URLs are added.
• Rollback behavior: revert the docs/metadata commit if needed. The baseline tag should remain immutable and should not be moved as part of rollback.

Tests

• cargo fmt --all -- --check
• cargo clippy
• cargo check --all-targets
• cargo test
• cargo test --all-targets

No new Rust tests were added because this PR is documentation/metadata-only.

Pull request overview

This pull request documents Mihoto’s fork provenance and governance baseline, and updates repository/package metadata links to the new fork while explicitly keeping the inherited runtime naming (mihoro, mihomo.service, etc.) unchanged.

Changes:

• Adds fork attribution and baseline details via NOTICE.md and docs/fork-baseline.md (including CI expectations and safety baseline rules).
• Updates README.md to reference the fork, link the provenance docs, and repoint badges/releases to Pectics/mihoto while keeping runtime naming as-is.
• Updates Cargo.toml package metadata (homepage, repository) to the fork.
