Fix regex in benchmarks cpu/disk_on_idle (BugFix)

[bladernr]

Description

• for disk_on_idle and cpu_on_idle, fix regex to resolve warning about invalid escape char in newer python3 versions. (older Python3 just silently passed it)
• Also added CLAUDE.md to gitignore to avoid accidentally pulling in Claude instructions when making commits. Fixes Invalid escape char in benchmarks/system/disk_on_idle and cpu_on_idle #2477

Tests

Tested on a fresh Bionic install to verify rawstrings does work back that far:

u@bionic-tester:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04 LTS
Release:        18.04
Codename:       bionic
u@bionic-tester:~$ python3 --version
Python 3.6.5
u@bionic-tester:~$ iostat -x -m 1 10 | python3 -c 'import sys, re; lines="".join(sys.stdin.readlines()); l=[float(n) for n in (re.findall(r"idle\n.*?(\S+)\n", lines))]; print(sum(l)/len(l),"%")'

u@bionic-tester:~$ iostat -x -m 1 10 | python3 -c 'import sys, re; lines="".join(sys.stdin.readlines()); l=[float(n) for n in (re.findall(r"util\n.*?(\S+)\n", lines))]; print(sum(l)/len(l),"%")'

For comparison, this is Resolute where the initial warnings appeared for me, showing before and after:

bladernr@resolute-test:~$ lsb_release -a

<string>:1: SyntaxWarning: "\S" is an invalid escape sequence. Such sequences will not work in the future. Did you mean "\\S"? A raw string is also an option.

Pull request overview

Fixes Python SyntaxWarning noise in benchmark jobs by making the regex patterns raw strings (so \S is treated as a regex escape rather than an invalid Python string escape), and prevents accidental commits of local Claude instruction files.

Changes:

• Update benchmarks/system/cpu_on_idle and benchmarks/system/disk_on_idle commands to use raw-string regex patterns in re.findall(...).
• Add CLAUDE.md to .gitignore.

File	Description
providers/base/units/benchmarks/jobs.pxu	Uses raw-string regex literals in two benchmark job commands to eliminate invalid-escape warnings on newer Python versions.
.gitignore	Ignores CLAUDE.md to avoid committing local tooling instructions.
