Closes #65

The capability table of the browser, per target: capabilityOf(browser-js, ...) follows the Browser column of section 2b of docs/design/JAVASCRIPT-AND-PHP.md, and an import of a package the table marks missing is an error at the import in torb build --target browser-js and torb check --every-target. docs/tooling/target-capabilities.md is the reader's copy, checked against the code by a test.

• feat(compiler): the table (project/capability.trb), missingCapabilitiesOf moved to project/missing-capability.trb (shared by the VM, build and check), enforcement in cli/build.trb and cli/targets.trb, tests, two command-line cases.
• docs: the page, links from torb-build / torb-check / the playground, status lines in the design records, regenerated skills/.

Decided by the loop:

• The helper lives in project/missing-capability.trb (not vm/run.trb): build must not import the VM, which already imports build.
• "The program" in torb build and torb check --every-target is every non-std/ module of the packages the entries reach (programPackagesOf), so a workspace member the entries do not use is not asked (check --every-target std/os stays clean). The VM path keeps asking the whole graph. Each missing package is reported once per import, in the file that imports it; std/ is not asked.
• std/dns is real on both browser targets (pure messages as values); the playground's other rows are unchanged, std/sandbox and std/machine stay real there.
• The PHP column is documented, not enforced; enforcement comes with the PHP target (#702).
• No syntax, native or std change, so nothing in seed/.

Not run locally (CI does): bootstrap, gates, the command-line expected output. The check --every-target block in tests/command-line/arguments.expected was corrected from the CI diff of the first run. Locally: torb format --check on the touched .trb files, torb docs skill docs skills --check, tools/check-commits.sh.

Closes #65 The capability table of the browser, per target: `capabilityOf(browser-js, ...)` follows the Browser column of section 2b of `docs/design/JAVASCRIPT-AND-PHP.md`, and an import of a package the table marks missing is an error at the import in `torb build --target browser-js` and `torb check --every-target`. `docs/tooling/target-capabilities.md` is the reader's copy, checked against the code by a test. - `feat(compiler)`: the table (`project/capability.trb`), `missingCapabilitiesOf` moved to `project/missing-capability.trb` (shared by the VM, build and check), enforcement in `cli/build.trb` and `cli/targets.trb`, tests, two command-line cases. - `docs`: the page, links from torb-build / torb-check / the playground, status lines in the design records, regenerated `skills/`. Decided by the loop: - The helper lives in `project/missing-capability.trb` (not `vm/run.trb`): build must not import the VM, which already imports build. - "The program" in `torb build` and `torb check --every-target` is every non-`std/` module of the packages the entries reach (`programPackagesOf`), so a workspace member the entries do not use is not asked (`check --every-target std/os` stays clean). The VM path keeps asking the whole graph. Each missing package is reported once per import, in the file that imports it; `std/` is not asked. - `std/dns` is real on both browser targets (pure messages as values); the playground's other rows are unchanged, `std/sandbox` and `std/machine` stay real there. - The PHP column is documented, not enforced; enforcement comes with the PHP target (#702). - No syntax, native or `std` change, so nothing in `seed/`. Not run locally (CI does): bootstrap, gates, the command-line expected output. The `check --every-target` block in `tests/command-line/arguments.expected` was corrected from the CI diff of the first run. Locally: `torb format --check` on the touched `.trb` files, `torb docs skill docs skills --check`, `tools/check-commits.sh`.

CI red on efd7f06: ci / tier A (linux-x64) -> ci / gates (3 red gates in gates.sh). No review yet; the next CI run brings me back.

1. check --every-target std/os: 83 problems on browser-js and browser-wasm64. The new enforcement flags std/process, std/http and std/network imports in the repo's own non-std/ modules (e.g. tools/html/elements.trb:13, tools/html/generate.trb:14). Either the gate's project set must not be checked against the browser targets, or the table/enforcement scope is wrong for this gate.
2. tests/command-line against .expected (unknown flags): tests/command-line/arguments.expected differs. The two new blocks are in a different order than the renderer prints them: the real output has 2 files, no problems then browser-wasm64: before browser-js:, and the The playground runs a program in the browser... note belongs to wasm64, the target-capabilities.md note to browser-js (and the summary line reads browser-wasm64, browser-js). See the CI diff at lines 735-757 of the tier A log.
3. docs check: docs/tooling/target-capabilities.md lacks the required sections ## What it does, ## Examples, ## Related; the summary is 245 chars (max 240); --target / --every-target on lines 17-18 must be double-quoted in the YAML.

No review yet; the next CI run brings me back. 1. `check --every-target std/os`: 83 problems on browser-js and browser-wasm64. The new enforcement flags `std/process`, `std/http` and `std/network` imports in the repo's own non-`std/` modules (e.g. `tools/html/elements.trb:13`, `tools/html/generate.trb:14`).

CI red on ea80a3b: ci / tier A (linux-x64) -> ci / gates. No review yet; the next CI run brings me back. I cannot read the job log with my account (404 on the run/job log endpoints), so I cannot name the failing gate. The pdisc, commit-messages, bootstrap, tier B and playground checks are green on this head, so the docs check finding of the previous round looks fixed. Please state which gate is still red (my earlier items 1 and 2 were check --every-target std/os and the order of the blocks in tests/command-line/arguments.expected).

Fixed on 03bb8b0. The tier A log of ea80a3b (job 28735, actions/jobs/28735/logs) showed three red gates left: docs check (docs/tooling/index.md generated part stale), docs index --check (same file) and docs skill --check (skills/torbscript/references/index.md stale). Cause: the summary of target-capabilities.md was shortened in the last commit but the generated indexes were not regenerated. Regenerated with torb docs index and torb docs skill docs skills; the diff is only that one summary line in three index files. Your earlier items 1 (check --every-target std/os) and 2 (block order in arguments.expected) are green on ea80a3b (the std/os lane passed in 18s, the command-line lane in 10s). Note for the job log: GET /repos/torbscript/language/actions/jobs/<job id>/logs works with the job id from actions/runs/<run>/jobs, not the index in the target URL.

Approved on 03bb8b0.

• Tests: ok. capability.test.trb pins the browser-js column, the unchanged machine and wasm64 columns, std/dns real, notes per target, and compares the docs page table with capabilityOf; two command-line cases pin the build and check output. CI green for this head (gates, tier A/B, bootstrap, playground, JS conformance, pdisc).
• Correctness: ok. The table follows section 2b; the check runs before lowering in torb build, and per target in problemsOfEveryTarget ahead of the lowering problems. The helper moved to project/missing-capability.trb with no VM import cycle. The VM path keeps the whole graph and std/ is not asked.
• Scope: ok. Matches #65 (PHP column documented, not enforced; no seed/ change).
• Security/data: ok. No secrets, ports, dependencies or storage formats touched.
• Docs: ok. New page, links, design-record status lines, regenerated skills/.

Non-blocking:

• TORB_BROWSER_JS_NODE is an escape hatch beyond the #65 text. It is documented and needed for the conformance leg, which uses Process.exit. Consider a follow-up that replaces it with an explicit flag if it should become a public interface.
