* fix: address git branch template review feedback

Address Copilot review feedback for branch_prefix help text, namespaced GIT_BRANCH_NAME fallback behavior, final-segment validation docs, and Bash UTF-8 byte reporting.

* fix: reject slug-scoped branch templates

Reject branch templates that place {slug} before {number}, because that makes namespace scanning depend on the generated feature slug and can reset numbering per feature name.

Assisted-by: Codex (model: GPT-5, autonomous)

* fix: ignore malformed timestamp refs when numbering

Align branch-number scanning with feature-branch validation so malformed timestamp-looking refs do not inflate sequential numbering. Also updates the stale git-common comment called out in review.

# Validate Feature Branch
Validate that the current Git branch follows the expected feature branch naming conventions.
## Prerequisites
- Check if Git is available by running `git rev-parse --is-inside-work-tree 2>/dev/null`
- If Git is not available, output a warning and skip validation:
```
[specify] Warning: Git repository not detected; skipped branch validation
```
## Validation Rules
Get the current branch name:
```bash
git rev-parse --abbrev-ref HEAD
```
The branch name's final path segment must start with one of these feature markers:
1. **Sequential**: `[0-9]{3,}-` (e.g., `001-feature-name`, `042-fix-bug`, `1000-big-feature`, `jdoe/web/008-guided-tour`)
2. **Timestamp**: `[0-9]{8}-[0-9]{6}-` (e.g., `20260319-143022-feature-name`, `jdoe/web/20260319-143022-feature-name`)
## Execution
If on a feature branch (matches either pattern):
- Output: `✓ On feature branch: <branch-name>`
- Check if the corresponding spec directory exists under `specs/`:
- For sequential branches, look for `specs/<prefix>-*` where prefix matches the numeric portion, regardless of branch namespace prefixes
- For timestamp branches, look for `specs/<prefix>-*` where prefix matches the `YYYYMMDD-HHMMSS` portion, regardless of branch namespace prefixes
- If spec directory exists: `✓ Spec directory found: <path>`
- If spec directory missing: `⚠ No spec directory found for prefix <prefix>`
If NOT on a feature branch:
- Output: `✗ Not on a feature branch. Current branch: <branch-name>`
- Output: `Feature branches should be named like: 001-feature-name, 20260319-143022-feature-name, or <namespace>/001-feature-name`
## Graceful Degradation
If Git is not installed or the directory is not a Git repository:
- Check the `SPECIFY_FEATURE` environment variable as a fallback
- If set, validate that value against the naming patterns
- If not set, skip validation with a warning
