Extends the tool to support both commit and tag formatting:

- Add git-formatted-tag mode for annotated tag formatting
- Add install subcommand to create symlinks in ~/.local/bin
- Extract shared code (runGitWithStdin, validateSubjectLength) to git.go
- Update module path to git.secluded.site/git-format

BREAKING CHANGE: Renamed from formatted-commit to git-format. Uninstall
the old binary and reinstall following README instructions. Run
git-format install to create symlinks, then invoke via git
formatted-commit or git formatted-tag.

Fixes type mismatch where breakingChange was declared as bool but used
as string after merge.

BREAKING CHANGE: The -B/--breaking flag now requires a description
argument instead of being a boolean. Use -B "description" instead of
just -B.

Wraps bluemonday output with html.UnescapeString so that characters like
quotes remain as literal "quotes" instead of "quotes".

Lines starting with 4+ spaces or a tab are now preserved verbatim,
fixing code block formatting in commit bodies.

Before:

    task.Method1()
    task.Method2()

Would become "task.Method1() task.Method2()" after reflowing.

The -B flag now accepts a string argument containing the breaking change
description instead of being a boolean flag. This description is
formatted and inserted as a BREAKING CHANGE: footer between the body and
git trailers, following the Conventional Commits specification.

The flag still adds ! to the subject line. When used with heredoc
syntax, multi-line breaking change descriptions are supported.

Also re-added the -a/--amend flag that was present in main but missing
from this feature branch.

When the -B flag is used to mark a commit as a breaking change, the tool
now validates that the body contains a BREAKING CHANGE: or BREAKING
CHANGES: footer. If not present, it returns a descriptive error
instructing users to document breaking change details in this footer.

Previously, formatBody processed each line independently. When input
text was already wrapped (but incorrectly), each line got rewrapped
separately, making the wrapping worse.

Now consecutive plain text lines are collected in a buffer, joined with
spaces to unwrap them, then passed to wordWrap once as a single
paragraph. Blank lines, bullet points, and numbered lists interrupt the
buffer to preserve paragraph boundaries and list formatting.

Commit messages are plaintext piped to 'git commit -F -' stdin,
so
HTML sanitization with bluemonday was unnecessary and harmful. It was
escaping characters like < and > that should remain literal in
commit
text.

Security is maintained through the stdin pipe preventing shell
injection.

Changed flag behavior:
- -a is now shorthand for --add (stage all modified files)
- --amend is now long-form only (no short flag)

Updated documentation in main.go, AGENTS.md, and README.md to reflect
new flag behavior.

Add comprehensive trailer validation following git's trailer
specification. Each trailer is validated for proper key:value format
with no whitespace allowed before or inside the key. Multiline values
are supported using RFC 822 folding with continuation lines
requiring whitespace indentation. Trailers are now properly assembled
into a block at the end of commit messages separated by blank lines.
