add --no-dl/-N option to skip downloads and set NODOWNLOAD=yes

Adds --no-dl/-N flag for use with --hintfile or --new. Skips wget,
inserts NODOWNLOAD=yes after MD5SUM_x86_64 in the hint file. Also
fixes README (correct paths, old command name, missing --delete/--clean
sections) and updates CLAUDE.md and bash completion accordingly.

 - `--hintfile` update: backs up to `.bak`, replaces old version string globally via `sed`, re-downloads both URLs to recalculate MD5 checksums. Skips download if value is `UNSUPPORTED` or `UNTESTED`.
 - `--new` with existing `.info`: copies `.info` as template, strips `PRGNAM`, `HOMEPAGE`, `MAINTAINER`, `EMAIL`, comments out `REQUIRES`, sets `ARCH="x86_64"`.
 - `--new` when hint already exists: backs up old, creates empty skeleton.
+- `--no-dl` / `-N`: skips all downloads; inserts `NODOWNLOAD=yes` after `MD5SUM_x86_64=` line. Works with `--hintfile` or `--new`. Error if used alone.
+- `--delete` / `-d`: removes hint file and `.bak` if present. Accepts multiple package names. Exits 2 on first missing file.
 - Downloads go to `/tmp/mkhint/download` (single shared temp file, deleted after md5 calculation).

+
+Updates the version string and adds `NODOWNLOAD=yes` to skip checksum verification in slackrepo:
+
+```bash
+mkhint --version 2.0.1 --hintfile mypackage --no-dl

 ### Create a new hint file from .info
 
 Generates a new hint file from the corresponding repository .info file:
 
 ```bash
-mkhintfile --version 1.2.3 --new mypackage
+mkhint --version 1.2.3 --new mypackage
 ```
 
 The .info file is copied as a template, unwanted variables (PRGNAM, HOMEPAGE, MAINTAINER, EMAIL) are removed, and ARCH is set to x86_64.

+```bash

 ### Create an empty hint file
 
 Creates a fresh hint file with empty variables:
 
 ```bash
-mkhintfile --new mypackage
+mkhint --new mypackage
 ```
 
 ### List hint files
 
 ```bash
-mkhintfile --list
+mkhint --list
+```
+
+### Delete a hint file
+
+Removes the hint file and its .bak backup if present:
+
+```bash
