fix: handle spaces in home directory paths on Windows (#94)

* fix: handle spaces in home directory paths on Windows

- expandHome: support ~\ (backslash) prefix and expand $HOME/${HOME}/%USERPROFILE% via os.ExpandEnv
- remove: use porcelain worktree list to avoid strings.Fields splitting paths with spaces
- shellenv: shell-quote arguments in Linux script(1) invocation to preserve spaces
- config template: quote $WT_PATH/$WT_MAIN in hook examples

Closes #93

* fix: expand Windows %VAR% style environment variables in config paths

os.ExpandEnv only handles $VAR and ${VAR}. Add expandWindowsEnv for
%USERPROFILE% and similar Windows-style variables, called on Windows only.

Follow-up from Codex review of #94.

* fix: expand env vars in tilde paths like ~/$TEAM/worktrees

The tilde branch returned early, skipping os.ExpandEnv. Now env
expansion runs on all paths including those starting with ~.

Follow-up from Codex review round 2.

* fix: check return value of os.Stdout.WriteString (errcheck)

feat: add fuzzy matching for interactive branch selection (#81)

* feat: add fuzzy matching for interactive branch selection

Replace exact-substring search with fuzzy matching in all interactive
selection prompts (checkout, remove, pr, mr). Uses sahilm/fuzzy
library. Prompts now start in search mode for immediate typing.

* docs: update examples and README for fuzzy matching

* fix: add TextExample to interactive examples and fix test index

The TestAllExamplesHaveConcreteSamples test requires all non-JSON
examples to have a TextExample. Also fix TestRemoveJSONExampleIndex
which hardcoded index [1] but the interactive example shifted it to [2].

fix: run checkout hooks when worktree already exists (#71) (#72)

Previously, `wt checkout` skipped pre/post checkout hooks when the
worktree already existed due to an early return. Now hooks run
regardless of whether the worktree is new or existing.

fix: resolve branch names case-insensitively against remote refs (#70)

When creating or checking out a branch, wt now queries `git ls-remote
--heads origin` and matches the user-provided branch name
case-insensitively. If the remote has a differently-cased branch (e.g.
`Feature/add-logging` vs `feature/add-logging`), wt uses the remote's
casing and prints a note to stderr.

Fixes #69
