chore: bump version to 0.10.0

* feat(init)!: make git extension opt-in and remove --no-git at v0.10.0

- Remove --no-git parameter from specify init command
- Remove git extension auto-installation from init flow
- Git repository initialization (git init) still runs when git is available
- Remove --no-git from all test invocations across the test suite
- Update docs to reflect opt-in git extension behavior
- Replace TestGitExtensionAutoInstall with TestGitExtensionOptIn tests

BREAKING CHANGE: specify init no longer auto-installs the git extension.
Use `specify extension add git` to install it explicitly.
The --no-git flag has been removed.

* refactor(scripts): remove git operations from core scripts

Git functionality is now entirely managed by the git extension.
Core scripts only handle directory-based feature creation and numbering.

- Remove has_git(), check_feature_branch(), git branch creation from core
- Simplify number detection to use only spec directory scanning
- Remove HAS_GIT output from get_feature_paths()
- Remove git remote fetching and branch querying
- Keep BRANCH_NAME output key for backward compatibility

* refactor: remove all git operations from core

- Remove is_git_repo() and init_git_repo() dead code from _utils.py
- Remove --branch-numbering from init command
- Remove git from 'specify check' (now extension-only)
- Update docs: git is optional prerequisite, check command description
- Fix tests to reflect no-git-in-core reality (fallback to main)

* refactor(scripts): remove directory scanning and branch fallback from core

Core scripts now resolve feature context exclusively from:
1. SPECIFY_FEATURE env var (set by git extension)
2. .specify/feature.json (persisted by specify command)

Removed find_feature_dir_by_prefix() and directory scanning heuristics —
these are the git extension's responsibility. Scripts error clearly when
no feature context is available.

* feat: introduce feature_numbering, deprecate branch_numbering in init-options

- specify command template now reads feature_numbering (preferred) with
  fallback to branch_numbering (deprecated) from init-options.json
- Git extension reads git-config.yml > feature_numbering > branch_numbering
- init now writes feature_numbering: sequential to init-options.json
- Deprecation warning emitted when branch_numbering is used as fallback

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* feat(scripts): persist SPECIFY_FEATURE_DIRECTORY env var to feature.json

When SPECIFY_FEATURE_DIRECTORY is set, get_feature_paths() now writes the
value to .specify/feature.json so future sessions without the env var can
still resolve the feature directory. The write is idempotent — it skips
when the file already contains the same value.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fix: address review feedback — error messages and docs

- Update error messages in common.sh and common.ps1 to reference
  SPECIFY_FEATURE_DIRECTORY instead of SPECIFY_FEATURE (which no longer
  resolves feature directories)
- Fix get_current_branch comment (returns empty string, not error)
- Update upgrade.md to reference SPECIFY_FEATURE_DIRECTORY with correct
  example paths
- Update local-development.md troubleshooting: replace stale 'Git step
  skipped' row with actionable git extension guidance

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fix(scripts): harden feature.json persistence

- Use json_escape in printf fallback when jq is unavailable (common.sh)
- Replace utf8NoBOM encoding with UTF8Encoding($false) for PowerShell
  5.1 compatibility (common.ps1)

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* refactor(scripts): remove dead feature_json_matches_feature_dir functions

These guards are no longer needed since the branch-name validation they
protected against has been removed from check-prerequisites.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* refactor(git-ext): rename create-new-feature to create-new-feature-branch

The git extension's script only creates the git branch — rename it to
reflect that responsibility. The core create-new-feature.sh/.ps1 handles
feature directory creation and feature.json persistence.

Also includes fixes from review feedback:
- common.sh: _persist_feature_json uses json_escape fallback
- common.ps1: Save-FeatureJson uses UTF8Encoding for PS 5.1 compat
- common.ps1: case-sensitive path stripping on non-Windows
- create-new-feature.sh/ps1: output both SPECIFY_FEATURE and
  SPECIFY_FEATURE_DIRECTORY
- setup-tasks.sh: fix stale 'Validate branch' comment

-## Using `--no-git` Flag
-
-The `--no-git` flag tells Spec Kit to **skip git repository initialization**. This is useful when:
-
-- You manage version control differently (Mercurial, SVN, etc.)
-- Your project is part of a larger monorepo with existing git setup
-- You're experimenting and don't want version control yet
-
-**During initial setup:**
 
 ```bash
-specify init my-project --integration copilot --no-git
+specify extension add git
 ```
 
-**During upgrade:**
+Projects that do not use Git can still work with Spec Kit by setting `SPECIFY_FEATURE_DIRECTORY` to the feature directory path before planning commands:
-
-```bash
-specify init --here --force --integration copilot --no-git
-```
-
-### What `--no-git` does NOT do
-
-❌ Does NOT prevent file updates
-❌ Does NOT skip slash command installation
-❌ Does NOT affect template merging
-
-It **only** skips running `git init` and creating the initial commit.
-
-### Working without Git
-
-If you use `--no-git`, you'll need to manage feature directories manually:
-
-**Set the `SPECIFY_FEATURE` environment variable** before using planning commands:
 
 ```bash
 # Bash/Zsh
-export SPECIFY_FEATURE="001-my-feature"
+export SPECIFY_FEATURE_DIRECTORY="specs/001-my-feature"
 
 # PowerShell
-$env:SPECIFY_FEATURE = "001-my-feature"
+$env:SPECIFY_FEATURE_DIRECTORY = "specs/001-my-feature"
 ```
 
-This tells Spec Kit which feature directory to use when creating specs, plans, and tasks.
+Alternatively, run the `/speckit.specify` command which creates `.specify/feature.json` automatically.
-
-**Why this matters:** Without git, Spec Kit can't detect your current branch name to determine the active feature. The environment variable provides that context manually.
