splitShellWords dropped every backslash outside single quotes, including inside double quotes where POSIX treats it as literal unless followed by $, backtick, ", \ or newline. Inside double quotes the backslash is now kept for ordinary characters; behaviour outside quotes is unchanged. Added tests next to the existing escaping test and a changelog fragment.

Closes #387

Read splitShellWords in full at 8721552 (src/attach.ts:67-116) and its caller buildCliCommand (src/attach.ts:118). Looks correct to me.

• The escape set '$"\\n' (src/attach.ts:76) is exactly POSIX 2.2.3's: before those characters the backslash is still dropped, before anything else it is kept. Outside quotes the branch is skipped by quote === '"', so existing behaviour is unchanged; inside single quotes ` never reaches this branch (src/attach.ts:81).
• Trailing \ inside an open " still appends the backslash and then throws the existing Unterminated quote error (src/attach.ts:109-113), so no new silent path.
• Built and ran test/attach-orchestration.test.js locally: 44/44 pass.

Only note (pre-existing, not from this change): \+newline inside double quotes yields a literal newline where POSIX would join lines; the unquoted path already behaves that way, so nothing to do here.

Looks correct to me.

Read splitShellWords in full at fafa17c (src/attach.ts:67-112) plus the callers (src/attach.ts:46,117,130,226,357,445, src/cli.ts:249). The one-line change at src/attach.ts:76 only fires on the escaping branch when quote === '"', so unquoted (a\ b) and single-quoted paths are untouched, and \", \\, \`, \$ inside double quotes still collapse as before — matching the POSIX rule the issue (#387) spells out. The trailing-backslash handling at :103-106 is unaffected (a dangling \ inside "…" still ends in the unterminated-quote throw).

Ran node --test test/attach-orchestration.test.js on the PR head: 44/44 pass, including the five new cases. verify, test (22/24/26) and DCO are green; the only pending check is tide.

Read splitShellWords in full at fafa17c plus all nine callers (src/attach.ts:46,117,130,226,357,380,445, src/cli.ts:249). Looks correct to me.

• src/attach.ts:76 only fires when quote === '"', so unquoted \ / \" handling (test/attach-orchestration.test.js:541) is untouched — confirmed by the existing test still passing.
• Inside "…", \" still reaches the escaping branch before the char === quote check at :93, so the quote is not closed early; \\, \` and \$ collapse to one char as POSIX requires.
• The rgBin caller at :46 regex-escapes each word after splitting, so a now-preserved backslash in a quoted path is escaped rather than passed raw.

Ran node --test test/attach-orchestration.test.js at the PR head: both splitShellWords tests pass, npm run build clean. Matches the behaviour #387 asked for (per #387: keep the backslash unless the next char is one of $ " `).

Not blocking, pre-existing: \<newline> inside double quotes yields a literal newline rather than being removed as a line continuation; nothing in the issue scope depends on it.
