Changes touching this path

• a verb run from a subdirectory finds the repo instead of advising an init that would nest a second one, path arguments rebase from the cwd the way a tester types them while view's globs stay root-relative, and the resolved root is named on stderr whenever cwd is not it eca43819 · dbf3dbe6…
• discovery asks one structural question at every depth instead of two that disagreed, so the installer's own dot-loot is never a repo even standing in it and unlock can no longer be handed that directory, while a damaged repo refuses in its own name from a subdirectory rather than letting an ancestor answer 974715e8 · dbf3dbe6…diff
• test scratch directories are named by one shared helper, common::scratch, from the process id and a per-process counter rather than the clock, so two tests asking for one tag at once are no longer handed one directory that the second caller empties and refills (the #2258 mechanism): 19 test files under crates/*/tests named a temp_dir path from SystemTime nanoseconds in 21 statements and now call fresh_dir or fresh_path, loot-cli files reaching it through mod common and loot-first exit_codes compiling the same std-only file by path, and revset_everywhere and plaintext_equality_census, which already counted, call it too. scratch_dirs.rs holds the #2258 pin, moved from revset_everywhere and aimed at the shared helper, red under the clock naming in 13 runs of 13 (0 passed and 1 failed, 1 to 16 of 400 directories handed twice), and a guard that walks every .rs file under crates/*/tests and refuses a temp_dir statement that reads the clock, red over the unconverted tree naming the 19 files (1 passed and 1 failed), red with buoy_exit put back (1 and 1) and red when the walk finds nothing (0 and 1), each restored green. no other test changes what it asserts. the workspace suite is green (4533 passed over 140 binaries, 13 ignored, from 4532 over 139: the guard is new and the pin moved into its own binary). test-only, so it owes no deploy (#2358) 6dd1e05b · dbf3dbe6…diff

Renames are not followed. loot's tree maps a path to an address, so a rename is a delete and an add. This list is the history of the name, not of the bytes.
