# Refactor: Code quality improvements (typo fix, dedup logic, remove
duplicates)

## Description
This PR addresses several code quality issues identified during a
codebase review:

1. **Fixed Typo in Public API**: Renamed `remomve_lrc` to [remove_lrc]
in [spotdl/utils/lrc.py] and updated all references.
2. **Extracted Duplicated Logic**: Moved LRC timestamp parsing logic
(which was identical in [embed_lyrics] and [embed_wav_file] in
[metadata.py] to a new reusable helper function [parse_lrc_timestamps]
in [lrc.py].
3. **Removed Duplicates**: Removed duplicate entries (`remix`, `live`,
`reverb`) from the `FORBIDDEN_WORDS` list in [spotdl/utils/matching.py].

Closes #2599

## Motivation and Context
These changes improve maintainability, verify public API naming
correctness, and adhere to DRY principles.
- The typo correction prevents confusion for future contributors.
- Extracting the LRC parsing logic simplifies
[metadata.py](cci:7://file:///home/eric/projetos_github/contribuicoes/spotify-downloader/spotdl/utils/metadata.py:0:0-0:0)
and makes the code reusable.
- Deduplicating the constant list avoids unnecessary iterations.

## How Has This Been Tested?
I ran the project's verification tools locally:
- `black` formatted all changed files correctly.
- `isort` verified import sorting.
- `pylint` score remains 10.00/10.
- `mypy` passed successfully with no type errors.

Testing Steps:
1.  Run `uv run black ./spotdl`
2.  Run `uv run isort --check --diff ./spotdl`
3.  Run `uv run pylint --fail-under 9 ./spotdl`
4.  Run `uv run mypy ./spotdl`
