fix(print): filter Stage 2 quality picker by selected media type (#214)

lpoptions -l only exposes the global quality list, so the picker offered every token for every media — the driver then rejected invalid pairs (e.g. Fast Economy on Premium Semigloss) at print time. Neither the Epson nor the Canon PPD carries standard *UIConstraints, so resolve the media-to-quality map from each driver's own data: Epson InkjetPrinter2 *EPIJUIConstraint forbid-rules in the machine bundle's PDEData.dat (non-media LHS terms evaluated against lpoptions defaults), Canon BJPrinter's binary cnb_<TableID>0.tbl record table via *CNIJNameTblPath/*CNIJTableID, and generic PPD *UIConstraints pairs.

MediaQualityConstraints picks the first non-empty source and fails open — queues without constraint data keep the full list. PrinterCapabilities gains qualityIDsByMediaType plus filtered qualities(forMediaType:)/allowsQuality accessors; the view model exposes availableQualities, clamps the pick on media change / seeding / panel apply-back, and substitutes a stale quality defensively in makeRequest so an invalid pair can never reach the ticket.

+
+## Root causes (pre-#201, historical v1)
+
+Two defects, both confirmed by reading the code:
+
+### 1. Ticket loss
+
+`ColorSyncSuppressor.captureOptions` (:133) was the only capture path. It
+funneled the whole `PMPrintSettings` object through `PMPrintSettingsToOptions`
+→ a space-separated `key=value` string, then `CupsOptionsFilter.filter`
+**dropped every `com.apple.*` key** (`CupsOptionsFilter.swift:49`) — i.e. it
+deliberately discarded `com.apple.print.PrintSettings`, the ticket the
+Epson/Canon raster filter reads. `lp` cannot reconstruct it, so the driver
+fell back to plain paper / normal quality.
+
+### 2. Override inversion
+
+`LpArgs.build` recorded every captured key in `addedKeys` (:67–73) and then
+*suppressed* the explicit Stage 2 value when the key was already present —
+media (:81), quality (:90), bypass (:102), orientation (:109), `PageSize`
+(:117). A Stage 2 dropdown change after a panel capture was silently ignored.
+
+### Dismissed hypothesis
+
+**argv tokenisation is safe** — `ProcessManager.runCaptured` hands an argv
+array to `Process`, never a shell. Space-containing `-o` values were
+preserved; this was checked and dismissed in the issue investigation and
+re-verified during the M12 audit.
+
+## Locked decisions (D1–D13)
+
+Decisions taken by the M12 megaplan; **locked — do not re-derive.**
+(`lp`/`LpArgs` mentions in this table name the deleted historical v1 path.)
+
+| # | Decision | Consequence |
+|---|----------|-------------|
+| D1 | Spooler lives in the **app target** (`Sources/ICCery/Print/`), not in `CupsService` | `ICCeryCore` stays AppKit-free (AGENTS §Package layout). `CupsService.printTarget` is **deleted**; `CupsService` keeps enumeration/capabilities/PPD only. The issue body's "in `CupsService`" is superseded — posted as errata on #201 |
+| D2 | Write **both** ColorSync vocabularies on the native path | AP_* (locked) **and** Quartz `PMColorMatchingMode=APCustomColorMatching` + `PMCustomColorMatchingProfile=""` + legacy `com.apple.print.PrintSettings.PMColorMatchingMode` + the nested `com.apple.print.printSettings` mirror. AGENTS §"Private ColorSync SPI — never mix" is **amended**: with `lp` gone there is one path and it carries both dictionaries (docs/14 decision table, "Set both if using NSPrintOperation") |
+| D3 | Ticket = `PMPrintSettings` **Data** + `PMPageFormat` **Data** + an `NSPrintInfo.dictionary()` plist fallback | `kPMDataFormatXMLDefault`. Restored via `PM*CreateWithDataRepresentation` → `PMCopy*` → `PMSessionValidate*` → `updateFromPM*`. Byte round-trip is unit-testable |
+| D4 | Delete `lp`; **keep** `CupsParsers` + `CupsOptionsFilter` | Parsers still drive capabilities (#183/#180/#181), media/quality key detection, driver-bypass detection, and the panel→Stage-2 apply-back mirror (#186). Only `LpArgs` dies |
+| D5 | Job granularity is **user-selectable**, default **one job per page** | New session-only `@Published var singleJobForAllPages = false`; Stage 2 checkbox `chkSingleSpoolJob`. Default preserves today's per-page notices and error attribution |
+| D6 | **Stage 2 always wins** over the rehydrated ticket | Unconditional overwrite of paper / media / quality / orientation. Mitigation for vendor companion-key desync: only write when the value differs from the ticket's current value, and log both (R4) |
+| D7 | Spool **silently** | `showsPrintPanel = false`, `showsProgressPanel = false`, `canSpawnSeparateThread = false`. Feedback stays on the existing `isPrinting` + `Notice`. No new system modal → XCUITest unaffected |
+| D8 | Verification = **recorder seam + PDF harness** | DEBUG `RecordingTargetSpooler` writes resolved ticket lines to `ICCERY_TEST_SPOOL_LOG` (replaces `ICCERY_TEST_LP_ARGV`); a real `NSPrintOperation` with `jobDisposition = .save` produces a PDF for geometry assertions |
+| D9 | Never scale; **warn + spool** | 1:1 always, anchored at the paper's top-left. `warn` when the DPI-derived size disagrees with the manifest `width_mm`/`height_mm` by >0.5 mm; warning `Notice` when the image exceeds the paper |
+| D10 | Device colour spaces implemented **and verified** for 1/3/4 channels at 8 and 16 bpc | Re-tag the decoded `CGImage` into `DeviceGray`/`DeviceRGB`/`DeviceCMYK` reusing the source `dataProvider` — **no resample, no bit-depth change**. Hardware gate covers RGB-8, RGB-16, DeviceGray-8 and CMYK-16 |
+| D11 | AirPrint detection + Stage 2 banner **in scope**, as its own issue | docs/14 §10.2 rules. Blocked-by #201 → filed as #202 |
+| D12 | Extract a **shared** `PMTicketBridge` | Single `@MainActor enum` owning every `PM*` call, with one documented `PMRelease` rule. `PrintPanelService` migrates onto it |
+| D13 | New milestone **M12 — Native print spool** | `milestone/m12-native-spool` from `develop`; #201 moves off the shipped M11 (id 34) |
+
+## Resolution
+
+Implemented on `milestone/m12-native-spool` (Phases 1–5, PRs #203–#207).
+(`LpArgs`/`lp` references below name deleted historical v1 artefacts.)
+
+- `PMTicketBridge` owns every `PM*` call; `PrintPanelService.showProperties`
+  returns `PanelCaptureResult` carrying a `PrintTicket` (layer ⑦ serialise).
+- `NativeTargetSpooler` rehydrates the ticket into a fresh `NSPrintInfo`
+  (S1–S14, docs/11 §native spool) and spools a headless `NSPrintOperation`
+  over `TargetPageCanvasView` — 1:1, top-left anchored, interpolation off.
+- `TicketWriteResolver` replaces `LpArgs.build`: Stage 2 always wins (D6),
+  both ColorSync vocabularies written (D2), no `raw` can ever appear.
+- `LpArgs`, `CupsService.printTarget`, the `lp` fixture and
+  `ICCERY_TEST_LP_ARGV` are deleted; `RecordingTargetSpooler` writes to
+  `ICCERY_TEST_SPOOL_LOG` for tests (D8).
+- AirPrint detection + Stage 2 warning badge shipped as #202 (D11).
