Incorporates the docs from #1079, verified against the plugin's
"added host option and normalized dev server URL" change: host option,
0.0.0.0/true normalization to localhost, CORS/allowedHosts handling.

- fix Czech grammar "ve chvíli, kde" -> "kdy" and unify tab/záložka wording
- use config.ini with parse_ini_file (NEON is not an INI format)
- document limitations: non-isolated stat functions, unlink on Windows, write rollback

- fix SMTP TLS default port (code defaults to 25, not 587)
- fix 'secure' description (deprecated alias of 'encryption', not value 'ssl')
- cs: add 'localhost' fallback for clientHost default
- document Message setters: addReplyTo(), setReturnPath(), setPriority() + priority constants
- document addEmbeddedFile() and SendmailMailer::setEnvelopeSender()
- expand FallbackMailer: $onFailure, addMailer(), FallbackMailerException
- document redirect/debugger config options

- decode(): parameter renamed $neon → $input to match the actual
signature (Neon::decode(string $input)); the old name broke named
arguments
- string quoting: added the reserved backtick to the list of characters
that require quoting (excluded by the lexer literal pattern)
- neon-lint: documented the optional [--debug] flag shown in its usage

Corrected untrue claims (dev server detection, type=module, what can be
loaded in production), broken examples (@s3mapper, extension option,
{preload} outputs), split mixed PHP/Latte code blocks, and fixed Czech
typos, mistranslations and broken links.

Documentation for the nette/command-line package (v1.x): Parser for
switches, options and positional arguments, and Console for colorful
ANSI terminal output. Adds meta.json plus aligned en/ and cs/ @home.texy.
