Normalize `nvm_version` output when `nvm_ls` returns "system vX" so alias and .nvmrc resolutions treat system correctly.
Add fast tests for system alias behavior in `nvm ls`, `nvm use`, and `nvm which`.
nvm.sh uses `NVM_SCRIPT_SOURCE="$_"` to detect its source location.
Adding `: nvm.sh` before each source line ensures `$_` is set correctly, preventing breakage when the previous command (e.g., `set -ex`) overwrites it.
Old Node.js versions have Makefiles with unquoted glob patterns like
`rm -f *.o` that fail in zsh's strict glob mode. By passing
SHELL=/bin/sh to make, we ensure POSIX-compliant shell behavior
regardless of what shell nvm is running in.
[Tests] `install.sh`: add tests for PROFILE=/dev/null profile skip
Verify that when PROFILE="/dev/null" is set:
- The "Profile not found" warning is suppressed
- Profile modification is skipped as expected

Previously, `nvm install Argon` would succeed by matching the LTS name
in the version description (e.g., "v4.9.1 (Latest LTS: Argon)"), but
`nvm uninstall Argon` would fail because "Argon" is not a valid alias or not a valid version.
Changes:
- Added pattern matching check in nvm_remote_version (nvm.sh:785-791)
- Skips check for implicit aliases (node, stable, etc.) to preserve
existing functionality
- Added unit tests to verify LTS names are rejected while version
numbers still work
After this fix:
- `nvm install Argon` → fails (use `nvm install lts/argon` instead)
- `nvm install 4` → still works
- `nvm install node` → still works
- `nvm install lts/argon` → still works
This makes install and uninstall behavior consistent.
Fixes#3474.
When `.nvmrc` or alias files contained comments (lines with `#`),
the `#` character could end up in the search pattern passed to sed,
causing "unterminated regular expression" errors because `#` is
used as the sed address delimiter.
This commit fixes the issue in two places:
1. `nvm_alias`: Strip comments from alias file contents before
returning them, and trim trailing whitespace
2. `nvm_ls`: Escape `#` characters in SEARCH_PATTERN so they're
treated as literal characters in the sed address
Fixes#3761
In theory, `npx nvmrc` can now be used to validate an `.nvmrc` file that `nvm` will support. Allowances have been made for future extensibility, and aliases may no longer contain a `#`.
Fixes#3336. Closes#2288.
