/resume fails with 'No conversations found' on Windows when multiple git worktrees exist (case-sensitive path comparison)

What's Wrong?

/resume reports "No conversations found to resume" even though conversation .jsonl files exist on disk and are being written correctly. This happens on Windows when the git repository has 2 or more worktrees.

After reverse-engineering the native binary (v2.1.38), I identified the exact root cause in the lsI function:

When there are 2+ git worktrees, the code takes a branch that reads the ~/.claude/projects/ directory and does a case-sensitive string comparison (M === V / === operator) between the actual folder name on disk and the folder name generated from the current working directory path via kR().

On Windows (NTFS), the filesystem is case-insensitive, so a project folder may have been created with a different casing than what the current path produces (e.g., My-Project on disk vs My-project from kR()). The === comparison fails, no sessions are matched, and /resume shows "No conversations found."

When there is only 1 worktree (or none), the code takes a different branch that uses path.join() to construct the folder path directly, which works fine on Windows because the filesystem resolves it case-insensitively.

What Should Happen?

/resume should list all previous conversations for the current project, regardless of the casing of the project folder name in ~/.claude/projects/. The folder name comparison in lsI should be case-insensitive on Windows.

Steps to Reproduce

1. On Windows, initialize a git repository in a directory with a mixed-case name (e.g., C:\Code\MyProject)
2. Start Claude Code and have at least one conversation (this creates a project folder in ~/.claude/projects/)
3. Note the exact casing of the folder created in ~/.claude/projects/ (e.g., C--Code-Myproject)
4. Create a second git worktree: git worktree add ../some-branch some-branch
5. Run /resume — it will report "No conversations found to resume"
6. Remove the extra worktree with git worktree remove some-branch — /resume works again

Root cause in code (extracted from the native binary):

// kR - converts path to folder name (preserves original case)
function kR(H) {
  return H.replace(/[^a-zA-Z0-9]/g, "-")
}

// lsI - lists sessions for resume
function lsI(H, $) {
  let A = OH(), L = uh()  // fs module, projects directory path

  // Branch 1: single or no worktree — works fine (uses path.join, filesystem resolves case)
  if (H.length <= 1) {
    let f = CL(), E = KX(f)
    return qQH(E, void 0, f)
  }

  // Branch 2: multiple worktrees — BUG IS HERE
  let D = H.map((f) => kR(f)), I = []
  let f = A.readdirSync(L)
  for (let E of f) {
    if (!E.isDirectory()) continue
    let M = E.name  // actual folder name on disk
    for (let _ = 0; _ < D.length; _++) {
      let V = D[_]  // generated folder name from path
      if (M === V || M.startsWith(V + "-")) {  // <-- case-sensitive comparison!
        I.push(...qQH(X3.join(L, M), void 0, H[_]))
        break
      }
    }
  }
  return R$H(I)
}

Suggested fix:

// Case-insensitive comparison on Windows
const eq = process.platform === 'win32'
  ? (a, b) => a.toLowerCase() === b.toLowerCase()
  : (a, b) => a === b

if (eq(M, V) || (process.platform === 'win32' ? M.toLowerCase().startsWith(V.toLowerCase() + "-") : M.startsWith(V + "-"))) {
