fix(husky): quote branch comparison to handle detached HEAD

[rnegron]

Problem

The pre-push hook compares branch names unquoted:

if [ $protected_branch = $current_branch ]

On a detached HEAD, git branch --show-current returns an empty string, so the test expands to [ master = ] and sh aborts with [: master: unary operator expected on every push from a detached-HEAD worktree.
Surfaced via hogli devex:feedback (reported twice).

Changes

Quote both operands so an empty current_branch is compared as a string, not dropped:

-if [ $protected_branch = $current_branch ]
+if [ "$protected_branch" = "$current_branch" ]

How did you test this code?

• Pushed this branch: the hook ran clean and ci:preflight passed.
• Shell repro of the empty-branch case (what a detached HEAD produces):
  • before (unquoted): sh: [: master: unary operator expected
  • after (quoted): no error, prints neq
  • master vs master still returns eq, so pushing to master is still blocked (behavior preserved).
• No automated test added: a shell-hook test for a one-token quoting fix would be low value and there is no existing harness for .husky/*.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Raúl surfaced this while triaging hogli devex:feedback entries for low-hanging fixes.
I (Claude) confirmed the root cause at .husky/pre-push:7, applied the quoting fix, and verified before/after behavior plus the preserved master-block in a scratch shell.
No repo skills were needed beyond the CI-failure triage that found it.

Trivial one-line quoting fix in a git hook script, no risky territory, verified behavior preserved.
