ci(lint): add typos spell checker and editorconfig

[panos-xyz]

Summary

• Add typos.toml with hex pattern exclusions and crate-ci/typos CI job for spell checking
• Add .editorconfig for consistent editor settings (UTF-8, LF line endings, indent rules)
• Add clippy check for feature-gated integration tests (morph-node --test it --features test-utils)

Test plan

• typos passes locally with zero findings
• CI typos job runs and passes
• Existing lint jobs unaffected

Summary by CodeRabbit

Chores

• Added a repository editor configuration to enforce consistent editor settings (line endings, charset, indentation, trailing-whitespace and final newline rules) across the project.
• Enhanced CI with an automated spelling check job and accompanying spelling configuration that ignores common hex-like tokens and explicitly treats "ser" as a valid word.

📝 Walkthrough

Walkthrough

Added repository editor settings via .editorconfig, introduced spelling-check configuration with typos.toml, and added a CI job (typos) to the lint workflow to run repository-wide spelling checks.

Changes

Cohort / File(s)	Summary
Editor configuration ​.editorconfig	Adds baseline editor rules: project root, LF line endings, UTF-8 charset, trim trailing whitespace, ensure final newline, 4-space default indent; overrides for Rust (max-line-length 100), YAML/YML (2-space indent), JSON/TOML (2-space indent), Markdown (no trim), and Makefiles (tabs).
Spell-check config typos.toml	Adds typos configuration: excludes .git, target, Cargo.toml, Cargo.lock, *.json; ignores hex-like patterns via case-insensitive regexes; whitelists the word ser.
CI workflow .github/workflows/lint.yml	Adds a new typos CI job using crate-ci/typos@v1 on ubuntu-latest to run repository spelling checks after checkout. No other CI steps modified.

Poem

🐰
A nibble at settings, neat and light,
Lines trimmed tidy, encoding right.
Typos chased in morning dew,
Quiet hops — the checks pass through.
A rabbit cheers, "All set — good night!"

In @.github/workflows/lint.yml:
- Around line 57-58: The CI step runs an invalid Clippy command referencing a
non-existent package feature and test target ("cargo clippy -p morph-node --test
it --features test-utils -- -D warnings"); either remove the invalid flags or
add the corresponding entries to Cargo.toml. Fix by editing the workflow to run
Clippy simply for the package (e.g., "cargo clippy -p morph-node -- -D
warnings") or, if you intended a feature/test, add a "test-utils" feature in
crates/node/Cargo.toml and a [[test]] named "it" in the crate so "--features
test-utils" and "--test it" are valid; ensure the symbols --test it, --features
test-utils, and -p morph-node are updated consistently.
