v0.5.4

The mod's look and commands: a band with a progress bar and the cause of a block, a padlock that reads as open, /pii allow instead of /pii off, and a clearer /pii doctor.

Changed

• Mod: the band above the prompt and the line under it are easier to read. The band shows a progress bar while the model downloads (starting · downloading the model ▰▰▰▰▰▰▰▱▱▱▱▱ 55% · 640 / 1,160 MB) and, when something blocks the mod, what it is in a few words with the next step (blocking · no sidecar token · run /pii doctor); it is drawn only while starting, paused, blocked or settling a policy change, and put away when all is well. The line under the prompt follows: ⏳ starting · downloading the model ▰▰▰▱▱▱ 55%, ⚠ blocking · another program holds the sidecar address.
• Mod: the padlock in the band is redrawn, 3 cells wide and 2 rows tall: closed with both legs of the arch on the body (teal when on, grey when broken), and open as the same padlock with the arch's right leg one pixel short (amber while starting, red while paused), so it reads as open and not as a shifted arch.
• Mod: /pii allow <category…> leaves a category readable; it replaces /pii off <category…>, whose name read like a way to switch nullpii off (it never was one: /pii pause is). The policy file keeps its off mode, and mask and ask are unchanged.
• Mod: the band has a button only while masking is paused (resume); while the mod starts or is blocked there is nothing to switch, so the old on button no longer shows. A first frame no longer reports a sidecar address that is not local before the session has started.
• Mod: /pii doctor says why the sidecar is unavailable once, on its first line; the lines that need the sidecar say only that they were not checked. When another program answers at the sidecar address, the fix is to pick a free port in the Sidecar URL option, not to start npx or Docker.
