* feat(scripts): add --dry-run flag to create-new-feature scripts
Add a --dry-run / -DryRun flag to both bash and PowerShell
create-new-feature scripts that computes the next branch name,
spec file path, and feature number without creating any branches,
directories, or files. This enables external tools to query the
next available name before running the full specify workflow.
When combined with --json, the output includes a DRY_RUN field.
Without --dry-run, behavior is completely unchanged.
Closes#1931

* fix(scripts): gate specs/ dir creation behind dry-run check
Dry-run was unconditionally creating the root specs/ directory via
mkdir -p / New-Item before the dry-run guard. This violated the
documented contract of zero side effects. Also adds returncode
assertion on git branch --list in tests and adds PowerShell dry-run
test coverage (skipped when pwsh unavailable).
Addresses review comments on #1998.

* fix: address PR review feedback
- Gate `mkdir -p $SPECS_DIR` behind DRY_RUN check (bash + PowerShell)
so dry-run creates zero directories
- Add returncode assertion on `git branch --list` in test
- Strengthen spec dir test to verify root `specs/` is not created
- Add PowerShell dry-run test class (5 tests, skipped without pwsh)
- Fix run_ps_script to use temp repo copy instead of project root

* fix: use git ls-remote for remote-aware dry-run numbering
Dry-run now queries remote branches via `git ls-remote --heads`
(read-only, no fetch) to account for remote-only branches when
computing the next sequential number. This prevents dry-run from
returning a number that already exists on a remote.
Added test verifying dry-run sees remote-only higher-numbered
branches and adjusts numbering accordingly.

* fix(scripts): deduplicate number extraction and branch scanning logic
Extract shared _extract_highest_number helper (bash) and
Get-HighestNumberFromNames (PowerShell) to eliminate duplicated
number extraction patterns between local branch and remote ref
scanning.
Add SkipFetch/skip_fetch parameter to check_existing_branches /
Get-NextBranchNumber so dry-run reuses the same function instead
of inlining duplicate max-of-branches-and-specs logic.

* fix(tests): use isolated paths for remote branch test
Move remote.git and second_clone directories under git_repo
instead of git_repo.parent to prevent path collisions with
parallel test workers.

* fix: address PR review feedback
- Set GIT_TERMINAL_PROMPT=0 for git ls-remote calls to prevent
credential prompts from blocking dry-run in automation scenarios
- Add returncode assertion to test_dry_run_with_timestamp git

* fix: support feature branch numbers with 4+ digits in common.sh and common.ps1
The sequential feature number pattern was hardcoded to exactly 3 digits
(`{3}`), causing branches like `1234-feature-name` to be rejected.
Changed to `{3,}` (3 or more digits) to support growing projects.
Also added a guard to exclude malformed timestamp patterns from being
accepted as sequential prefixes.
Closes#344

* fix: narrow timestamp guard and use [long] to prevent overflow
- Change [int] to [long] in PowerShell Get-CurrentBranch to avoid
overflow for large feature numbers (>2,147,483,647)
- Narrow malformed-timestamp exclusion from ^[0-9]+-[0-9]{6}- to
^[0-9]{7}-[0-9]{6}- so valid sequential branches like
004-123456-fix-bug are not rejected

* test: add regression tests for 4+ digit feature branch support
Cover check_feature_branch and find_feature_dir_by_prefix with 4-digit
sequential prefixes, as requested in PR review #2040.

* fix: reject timestamp-like branches without trailing slug
Branches like "20260319-143022" (no "-<name>" suffix) were incorrectly
accepted as sequential prefixes. Add explicit rejection for 7-or-8
digit date + 6-digit time patterns with no trailing slug, in both
common.sh and common.ps1.

* feat(scripts): add --allow-existing-branch flag to create-new-feature
Add an --allow-existing-branch / -AllowExistingBranch flag to both
bash and PowerShell create-new-feature scripts. When the target branch
already exists, the script switches to it instead of failing. The spec
directory and template are still created if missing, but existing
spec.md files are not overwritten (prevents data loss on re-runs).
The flag is opt-in, so existing behavior is completely unchanged
without it. This enables worktree-based workflows and CI/CD pipelines
that create branches externally before running speckit.specify.
Relates to #1931. Also addresses #1680, #841, #1921.

* fix: address PR review feedback for allow-existing-branch
- Make checkout failure fatal instead of suppressing with || true (bash)
- Check $LASTEXITCODE after git checkout in PowerShell
- Use Test-Path -PathType Leaf for spec file existence check (PS)
- Add PowerShell static assertion test for -AllowExistingBranch flag
