Replace the flat character-class regex for SHELL_SAFE_COMMAND_PATTERN with
a token-aware alternation. The parser now recognizes explicit tokens
(`&&`, `||`, balanced single/double quotes, whitespace, and an unquoted
safe-char run) instead of a bag of characters, which lets us extend the
accepted grammar without loosening the guarantees.
New surface area, with tests:
- logical OR chaining (`make build || make clean`)
- shell globs and bang (`rm *.tmp`, `cp src/?.js dist/`, `! grep -q foo`)
- single-quoted arguments are now treated as balanced runs rather than
rejected per-character
Preserved surface area:
- && chaining, balanced "..." and '...' quotes, the previous safe path /
argument characters, and the existing error-path contract in
ApplicationDeploymentJob::validateShellSafeCommand().
Also refreshes the user-facing validation messages in General.php so the
allow/deny list shown on failure matches the new grammar.

Strip advisory identifiers (GHSA-*) from describe blocks, test
docblocks, and inline comments. Replace with plain descriptive
labels. Also clean up FQCNs to use imported class names and minor
style fixes (string concatenation spacing).
Permit single-quoted arguments in SHELL_SAFE_COMMAND_PATTERN while
keeping dangerous metacharacters blocked, and add security test cases
for quoted --entrypoint and --hostname values.
Add shellSafeCommandRules() validation to install_command, build_command,
and start_command fields in both the Livewire UI and REST API layers.
These fields previously accepted arbitrary strings without validation,
unlike other shell-adjacent fields which already used this pattern.
Also adds comprehensive tests for rejection of dangerous input and
acceptance of legitimate build commands.

Previously, the SHELL_SAFE_COMMAND_PATTERN was overly restrictive and blocked
legitimate characters needed for common Docker operations:
- Allow & for command chaining with && in multi-step build commands
- Allow " for build arguments with spaces (e.g., --build-arg KEY="value")
Update validation messages to reflect the new allowed operators and refactor
code to use imports instead of full class paths for better readability.
- Add -i flag to explicitly specify ssh key path in git ls-remote operations
- Remove static $rules properties in favor of dynamic rules() method
- Fix test syntax error
